The ADL8142S from Analog Devices is a pHEMT Low Noise Amplifier MMIC 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. This LNA has a power-added efficiency of up to 21% and requires a DC supply of 2 V while drawing 25 mA of current. It has been developed for commercial space applications and has wafer diffusion lot traceability, radiation lot acceptance tests (RLAT), total ionizing dose (TID), and radiation benchmarking with single event latch-up (SEL). This LNA is available in an LFCSP package that measures 2 x 2 mm and is ideal for geosynchronous high throughput satellite (GEO HTS), low earth orbit (LEO) space payloads, and satellite communication applications.
