Skyware Global DR5 5W Universal Ku-Band Dual Pol VSAT Transceiver

The Skyware Global DR5 Universal VSAT Transceiver supports all known modems and may be switched between any of the Ku-outbound (receive) sub-bands.

This transceiver platform includes a DIP (diplexer) and is fitted with a dual polarization receiver.

This single transceiver, supports all known modems and may be switched between all Ku-outbound (receive) sub-bands and both Co- and Crosspolarization. These features offer huge logistical advantages over the existing first generation VSAT systems built using discrete components.

This breakthrough in performance and flexibility was achieved using Skyware’s patent pending, “flexible downconverter” architecture.

With Skyware’s unique PLL (phase locked loop) IC (integrated circuit), the result is a high stability PLL, at the same price as the lower performance DRO.

The integrated 5 W BUC (block up converter) was designed with high efficiency and linearity in mind, thus reducing operating temperatures, increasing reliability and minimizing environmental footprint.

In addition, the integrated OMT (ortho-mode transducer) and TRF (transmit reject filter) guarantee system critical EIRP
and G/T at installation.

Comtech X-Band Low-Noise Block Down Converter (LNB) Series

Comtech’s X-Band Low-Noise Block Down Converter Series (LNB) meets or exceeds system requirements for commercial and military geosynchronous satellites worldwide.

Their compact design and rugged construction make them ideal for transportable applications and
severe environments. They have a comprehensive set of options to accommodate systems ranging from Very Small Amplifier Terminal
(VSATs) to major earth stations. The X-Band LNB allows for interfacing, at the antenna, with our LPOD family of X-Band outdoor BUCs
for sourcing of the LNB bias voltage and high stability reference in either single or redundant configurations.

Technology

The amplifiers incorporate both HEMT devices for low-noise temperature performance and GaAs FET devices for low intermodulation.
The units use surface mounted components for robotic manufacturing techniques, thereby ensuring maximum product consistency and
enhanced reliability. The X-Band LNB includes integrated filtering to address adjacent power issues peculiar to demanding X-Band
terminals.

Reliability

The amplifier series utilizes proprietary circuitry and high-quality components to achieve an MTBF in excess of 160,000 hours. Each unit
is subjected to a 72-hour burn-in and temperature cycled from -40 to 140°F (-40 to +60°C).

Construction

The LNBs are housed in waterproof enclosures with small profiles to better accommodate redundancy configurations. The enclosures
also provide a pressurizable, integral waveguide flange.

Accessories

Transmit reject filters, cables and other integration materials are offered as required.

Subsystems

1+1 (one backup for one primary) and 1+2 (one backup for two primary) redundant LNB systems are available, complete with mounting
plate, brackets and indoor redundancy controller/power supply. Transmit reject filters, cables and other integration materials are offered
as required.

Comtech MCED-100 and MCDD-100 Embedding and Detecting Devices

Building on Comtech’s leadership in providing equipment to optimize the quality of satellite links, they are introducing the MetaCarrier™ Carrier Identification Embedding and Detecting Devices, the MetaCarrier Embedding Device (MCED-100) and the MetaCarrier Detecting Device (MCDD-100).

The MCED-100 places the MetaCarrier Carrier Identification on the referenced carrier, and the MCDD-100 receives it. These patent-pending products use spread spectrum technology for a complete MetaCarrier embedding and decoding solution.

The MCED-100 embeds a unique carrier identification sequence for a transmission carrier. The MCDD-100 decodes an embedded unique carrier identification sequence for a transmission carrier. In a typical network, there can be as many MCED-100s as there are modulating devices, and a smaller number of MCDD-100s to verify the presence of the MetaCarrier on each carrier. In an interference situation, the MCDD-100 may be used to decode the MetaCarrier of an interfering carrier that may not be part of one’s own transmission network, as long as the interfering carrier has a MetaCarrier embedded.

The MCED-100 and the MCDD-100 can operate in both non-interfered and interfered conditions, and are ideally suited for SCPC, MCPC and video satellite carrier transmissions. By using the MetaCarrier concept, a low-speed data sequence containing information about the transmission carrier is spread using Direct Sequence Spread Spectrum (DSSS), and then combined with the transmission “desired” carrier to produce a composite carrier with an embedded CID.

Comtech CRS-500 1:N Modem Redundancy System

The Comtech CRS-500 1:N Modem Redundancy
System
is intended for hub applications, and provides automatic or manual protection for up to 10 Traffic (or prime) modems with one redundant (or standby) modem.

The CRS-500 supports the CDM-625 and CDM-750 modems for select interfaces. The CDM-625 is supported when using the 10/100 Packet Processor mode. The CDM-750 is supported when using the G.703 interface or the Gig-E interface in all modes.

As shown in the figure, the CRS-500 is a flexible, modular-type architecture, composed of a Control Switch Unit (CSU), Data Switch Unit (DSU) and
optional IF Switch Units (ISUs).

A key feature of the CRS-500 architecture is its ability to allow the redundant modem to ‘bridge’ a traffic modem. The CRS-500 controller automatically configures the redundant modem to match the bridged traffic modem’s configuration. The CRS-500 also provides a copy of the bridged traffic modem’s TX traffic data to the redundant modem. When using the IF Switch Units (ISUs), it additionally routes the bridged traffic modem’s RX IF.

CRS-500 Control Switch Unit (CSU)

The CSU is the controller of the CRS-500 Redundancy System and consumes only 1RU of rack space. It contains field-replaceable modules such as the CRS-530 controller and dual, hot-swappable Power Supply Units (PSUs).The configuration of each traffic modem is stored in the CRS-530 controller. This information is used to program the redundant modem if a traffic modem fails. The CSU contains an extensive M&C system and is fully controllable from the front panel or from external 10/100 Ethernet or EIA-232C/485 ports located on the back side of the CSU unit, (on the CRS-530 module). Ethernet is used by the switch to communicate to all modems. A 10/100 Ethernet M&C connection goes to/from each modem to the CSU.

SED Systems Decimator D3 Spectrum Analyzer

The SED Decimator D3 is a third generation spectrum measurement and analysis card providing high-end performance at a low price.

It can function as either an independent spectrum analyzer or can easily be integrated into a satellite terminal, equipment enclosure or as part of a larger measurement network.

Decimator is only 4” x 7” x 0.8” and is therefore ideal for integration into small spaces. It can be installed in any enclosure or computer chassis. It is a half size PCI express card and can be installed in an available computer PCIe slot, providing power to the card. Alternately, it can be mounted on standoffs and powered through a 3-pin connector (12 and 3.3 to 5 Vdc) for integration into any enclosure.

It uses state of the art digital technology and Fast Fourier Transformations to make quick and accurate measurements. With a very low noise floor and large dynamic range, it is well-suited to measurement of any type of satellite carrier, including very small carriers, beacon signals and for carrier monitoring applications. Decimator accepts all signals from 5 MHz to 3 GHz and input power levels ranging from –110 to +5 dBm. RBW varies from 1 Hz to 7.4 MHz. The Decimator can be connected to an external 10 MHz reference for improved frequency accuracy and stability. All data communications with the Decimator occurs via its built-in Ethernet port.

The Decimator’s powerful Graphical User Interface (GUI) is available using any standard web browser. No additional software is required. The GUI is very easy to use and operates like most traditional spectrum analyzers. It provides user-selectable colors for markers and traces, allows storage of multiple traces and provides measurement reporting. The Decimator GUI also includes two powerful applications: The built-in
Carrier Monitoring function, provides notification via email or SNMP of carrier measurements that exceed user-defined limits, offering you peace of mind that up to 100 of your carriers are operating as expected. The Decimator provides network access to all technical staff connected to the facility network or a corporate wide area network. This allows all technical staff the ability to monitor feeds and carriers at any time and from any location in the world using only a web browser.

For integration into a satellite terminal or measurement system, the Decimator can be operated via its built-in GUI or the user can create a separate user interface using the publicly available API. An SNMP status interface is also provided.
