High Power, X-Band SSPAs & BUCs with Low Leakage Capabilities

Comtech Xicom Technology has introduced a new series of industry-leading X-band solid-state power amplifiers (SSPAs) and block up-converters (BUCs). The new XTSLIN-25X, XTSLIN-80X, XTSLIN-150X and XTSLIN-250X lines of linear power X-band amplifiers provide the highest linear power density solutions available while drawing very low prime power and operating in the toughest environments.

The units are designed to meet all RF requirements in challenging X-band networks, including Wideband Global Satellite (WGS) requirements and support for multi-carrier systems. X-band is one of the most difficult satellite communications bands to operate in because the transmit and receive bands are directly adjacent. Xicom’s proprietary very-low leakage designs ensure that any transmit noise or spurious signals in the receive band is attenuated and contained to avoid disruption of the received signal, enabling multi-carrier operation with low Passive Intermodulation (PIM) antennas.

These X-band SSPAs are all offered with optional built-in up-converters; with a range of monitor and control interfaces including SNMP; and options for redundancy or output power combining. The compact size and high efficiency of these units provide unparalleled linear power density, achieving 25W of linear output power (using MIL-STD-188-164 definition) with a 5.3 lb. package; and 150 W linear output power with a 32 lb. package. These units operate air-cooled in -40C to +60C temperatures and meet stringent outdoor environmental requirements per MIL-STD-810G.

According to Mark Schmeichel, Senior Vice President, and General Manager for Comtech Xicom Technology, the X-band SSPAs take advantage of the latest GaN technology for high efficiency and power density, and also incorporate Xicom’s extensive institutional knowledge gained by developing high-power X-band tube-based amplifiers with extremely low leakage. With the addition of these innovative GaN-based SSPA products, Xicom has become a clear global leader in X-band satcom uplink amplifiers.

The company is showcasing the product line to satcom integrators and operators visiting the Comtech Xicom Technology Booth (#1401) at SATELLITE 2019 from May 6-9, in Washington, DC.
