STUART, Fla. – Smiths Interconnect in Stuart, Fla., is introducing the Ku-band high power transceiver (HPT) airborne satellite communications (SATCOM) system for commercial aircraft.

Integrating a gallium nitride (GaN) power amplifier, upconverters, downconverters, and digital control technology to offer a modular yet easily maintained system with advanced interoperability features and several built-in-test (BIT) functions.

Leveraging the maximum channel temperature limit of GaN devices, along with built-in solid-state power amplifier protection against high voltage standing wave ration (VSWR) loads, the 25 Watt HPT system offers standard reliability and stability for commercial airborne systems.

For applications that require additional commercial air transport use assurance, an optional vibration-insensitive oven-controlled crystal oscillator (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. For more information contact Smiths Interconnect online at www.smithsinterconnect.com.
