Smiths Interconnect (appearing in booth #1441 at the International Microwave Symposium (IMS) in Honolulu, Hawaii), has released the Ku-Band High Power Transceiver (HPT).

This HPT is a complete airborne SatCom solution, integrating a GaN SSPA, upconverters, downconverters, and digital control technology to offer a highly modular yet easily maintained system complete with advanced 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 loads, the 25W HPT system offers extremely high standard reliability and stability for commercial airbone systems. 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 from 13.75 to 14.5 GHz from an IF frequency of 950 to 1700 MHz with a gain variation of less than 1.0 dB over any 36 MHz band and provides the frequency block down conversion from 10.7 to 11.7 GHz to the low band IF of 950-1950 MHz or from 11.7 to 12.75 GHz to the high band IF of 1100-2150 MHz. The Receive bands are selectable with commands over the Ethernet bus.
