The CMX90A705 from CML Microcircuits is a Two-Stage GaN Power Amplifier that operates from 27.5 to 31 GHz. It delivers a saturated output power of 5.5 W (~37.4 dBm) with a small signal gain of 16.5 dB and PAE of 22%. This Ka-Band amplifier is fabricated using a state-of-the-art 0.15 µm gate length GaN-on-SiC process. It requires a DC supply of 22 to 28 V and consumes 860 mA of current.
The CMX90A705 incorporates on-chip 50 Ohms nominal matching with integrated DC blocking capacitors at the I/O ports. This power amplifier is available in an AQFN-12 package that measures 4 x 4 mm. It can be used as both driver stage and final stage power amplifier in commercial satellite communication terminals, residential satellite internet, telecommunication, and commercial VSAT applications.
