TRAK launches compact 25W Ku-band transceiver incorporating GaN SSPA for commercial airborne applications
TRAK Microwave (a Smiths Microwave brand that designs and manufactures RF and microwave assemblies, subsystems, components and time & frequency systems for defense, space and commercial applications) says that its new HPT Ku-band transceiver functions as a complete airborne SatCom solution, integrating the necessary gallium nitride (GaN) solid-state power amplifier (SSPA), up-converters, down-converters and digital control technology to offer a highly modular yet easily maintained system complete with interoperability features and multiple built-in-test (BIT) functions.
Leveraging the higher maximum channel temperature limit of GaN devices along with built-in SSPA protection against high VSWR (voltage standing wave ratio) loads, the 25W HPT system offers high standard reliability and stability, it is claimed. For applications that require additional commercial air transport use assurance, an optional vibration-insensitive OCXO installed on a vibration isolation platform is available.
The HPT can transmit at 13.75-14.5GHz from an IF frequency of 950-1700MHz with a gain variation of less than 1.0 dB over any 36MHz band and provides the frequency block down-conversion from 10.7-11.7GHz to the low-band IF of 950-1950MHz or from 11.7-12.75GHz to the high-band IF of 1100-2150MHz. The receive bands are selectable with commands over the Ethernet bus.
Qualified for commercial airborne environments, this type-N RF TX/RX and TNC IF TX/RX compact and highly integrated device operates at temperatures from -15°C to +55°C.
