CML Micro launches the CMX90A705, a Ka-band gallium nitride (GaN) power amplifier that represents a cost-effective building block for commercial high-volume satellite communication terminals.
The CMX90A705 is a packaged two-stage GaN linear power amplifier delivering +37.4 dBm (5.5 W) of saturated power, covering a frequency range of 27.5 to 31 GHz and with 16.5 dB of small signal gain. It can be used as both driver and the final stage of power amplification in satellite communication terminals.
The PA has been designed for ease of integration, with RF input and output ports nominally matched to 50 Ω and integrated DC blocking capacitors. Drain and gate feed decoupling capacitors suitable for QPSK type modulation are incorporated into the evaluation board.
The active device is fabricated using a world-leading 0.15 µm gate length GaN-on-silicon carbide (SiC) process and presented in a small form factor, 4x4mm thermally enhanced air-cavity Quad Flat No-Lead (QFN) packaging.
