TRAK launches Ku-band block upconverter with integrated GaN SSPA

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) has launched the Model MFC147 block upconverter (BUC), which provides 13.75-14.50GHz coverage for civilian and military aviation Ku-band SatCom applications, including in-flight entertainment (IFE) systems and unmanned airborne vehicle (UAV) communications.

The unit features a ruggedized design and innovative thermal management technique to withstand challenging airborne environments by using SMT construction with no open die. Input frequency to the block upconverter is 950-1700MHz, with Ku-band output of +12-17dBm.

An integrated, low-noise gallium nitride (GaN) solid-state power amplifier (SSPA) provides 25W minimum output power, providing better than -120dBc/Hz noise power (-140dBc/Hz typical) and less than -22dBc spectral regrowth (OQPSK). 

The MFC147 includes built-in test (BIT), temperature monitoring and forward/reverse (FWD/REV) power detectors, all monitored via standard serial commands. Drain voltage control reduces thermal dissipation at lower power output levels. The BUC includes 0 to +7dB gain expansion and 30dB digital gain control for optimum SSPA performance. The device is offered as EAR99 and is not subject to export restrictions.
