GaN SSPA Powers Ku Band Block Upconverter

The Model MFC147 "PowerBuc" from TRAK Microwave, a Smiths Interconnnect brand, 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. Request pricing and additional information from our up/downconverter page .
