GaN amplifier Powers Ku Band Block Upconverter
Trak Microwave has introduced a Ku Band Block Upconverter (BUC) with integrated low-noise, GaN, Solid State Power Amplifier (SSPA). The model MFC147 provides 13.75 to 14.50GHz 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 innovative thermal management technique to withstand challenging airborne environments using SMT construction with no open die. Input frequency to the Block Upconverter (BUC) is 950-1700 MHz, with Ku-band output of +12 to +17 dBm.
The 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 not subject to export restrictions.
