The CHA4252-QKB from United Monolithic Semiconductors is a 3-Stage GaAs Power Amplifier MMIC that operates from 27.5 to 30 GHz. It delivers a saturated output power of 25 dBm (~0.316 W) with a linear gain of 30 dB and a power-added efficiency (PAE) of 30%. The amplifier requires a DC supply of 10 to 18 V and consumes 80 mA of current. This RoHS-compliant amplifier is available in a 24-lead QFN package that measures 4 x 4 mm, and it is ideal for space and other wide range of microwave applications.
