Power amplifier CMX90A705

linear

The CMX90A705 is a packaged two-stage Ka band GaN linear power amplifier delivering 37.4 dBm (5.5 W) of saturated power with 16.5 dB of small signal gain. It can be used as both driver stage and final stage PA in a commercial satellite communication terminal. RF ports are nominally matched to 50 Ω for ease of use, with integrated DC blocking capacitors at RF input and output. The PCB will incorporate drain and gate feed decoupling capacitors suitable for modulated signals e.g. QPSK. The active device is fabricated using state-of-the-art 0.15 µm gate length GaN-on-SiC process and packaged in a small form factor, 4 x 4 mm thermally enhanced plastic air-cavity QFN.
