GaN SSPA Powers Ku Band Block Upconverter

The Model MFC147 "PowerBuc" from TRAK Microwave provides 13.75 to 14.50 GHz coverage for civilian and military aviation Ku-band SATCOM applications, including In-Flight Entertainment (IFE) systems and UAV communications. The unit features a ruggedized design and an innovative thermal management technique utilizing SMT construction with no open die to withstand challenging airborne environments .

Input frequency to the Block Upconverter (BUC) is 950-1700 MHz, with Ku-band output of +12 to +17 dBm. An integrated, low-noise, GaN, Solid State Power Amplifier (SSPA) provides 25 watts minimum output power providing better than -120 dBc/Hz noise power (-140 dBc/Hz typical) and <-22 dBc spectral regrowth (OQPSK).

The MFC147 includes built-in test (BIT), temperature monitoring and 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 +7 dB gain expansion and 30 dB digital gain control for optimum SSPA performance. The device is offered as EAR99 and is not subject to export restrictions.
