The ADH8411S from Analog Devices is a GaAs pHEMT Low Noise Amplifier MMIC that operates from 0.01 to 10 GHz. It delivers a saturated output power of 20.5 dBm with a gain of 14 dB and has a noise figure of 2 dB. This LNA has an OIP3 of 33 dBm and a power-added efficiency of up to 34%. It can also function as a local oscillator (LO) driver for many Analog Devices’ balanced, in-phase/quadrature (I/Q), or image rejection mixers. The LNA supports aerospace applications and includes commercial space features like water diffusion lot traceability, burn-in, life test & deltas analysis, radiation lot acceptance test (RLAT), and total ionizing dose (TID). It requires a DC supply of 5 V and consumes 55 mA of current.
The ADH8411S is available in a 6-lead LFCSP package that measures 2 x 2 mm with internally matched inputs and outputs for SMT-based high-capacity microwave applications. It is ideal for LEO satellites and military communications applications.
