The CHA7250-QAB from United Monolithic Semiconductors (UMS) is a Two-Stage MMIC Power Amplifier that operates from 10 to 12.75 GHz. It delivers a saturated output power of 10 W (~40 dBm) with a gain of 20 dB, and has a Power Added Efficiency (PAE) of 37%. This amplifier IC is manufactured on UMS’ proprietary 150 nm GaN-on-SiC (AlGaN/GaN-on-SiC) technology and exhibits high linearity and efficiency. It requires a DC supply of 20 V, consumes 130 mA of current and 12 W of power. This RoHS-compliant PA is available in a surface-mount package that measures 6 x 6 mm and is ideal for point-to-point radio applications.
