Ku-band block upconverter integrates GaN solid-state power amplifier
The device features a ruggedized design and innovative thermal management technique to withstand challenging airborne environments utilizing SMT construction with no open die. Input frequency to the Block Upconverter (BUC) is 950 to 1700 MHz, with Ku-band output of +12 to +17 dBm. An integrated, low-noise, GaN, solid state power amplifier (SSPA) provides 25 W 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.
