CHA6161-QKB

The CHA6161-QKB from United Monolithic Semiconductors is a 3-Stage Power Amplifier MMIC that operates from 17 to 21.5 GHz. It delivers a saturated output power of up to 34.5 dBm (2.8 W) with a linear gain of 32 dB and a power-added efficiency of up to 43%. This three-stage power amplifier is developed on a robust GaN on SiC HEMT process and has a return loss of 8 dB (input/output). It requires a DC supply of 12-20 V and consumes less than 1300 mA of drain current. This RoHS-compliant amplifier is available in a 24-lead QFN package measuring 4 x 4 x 0.85 mm and is ideal for space and other wide range of microwave applications.
