The ADL8142 from Analog Devices is a GaAs pHEMT MMIC Low Noise Amplifier that operates from 23 to 31 GHz. It delivers a gain of 29 dB with a noise figure of less than 1.8 dB and has a saturated output power of 10 dBm. The LNA has a power added efficiency of more than 18%. It requires a DC supply of 2 V and consumes 25 mA of current. The amplifier is available in an RoHS-compliant LFCSP package that measures 2 x 2 mm with AC-coupled inputs and outputs that are internally matched to 50 ohms. It is ideal for use in satellite communications, telecommunications and civilian radar applications.
