GENERAL DESCRIPTION

The ADL8142-2C-CSL is a gallium arsenide (GaAs), monolithic

microwave integrated circuit (MMIC), pseudomorphic high electron

mobility transistor (pHEMT), low noise wideband amplifier that

operates from 23 GHz to 31 GHz. The ADL8142-2C-CSL provides

a typical gain of 26.5 dB, a 1.8 dB typical noise figure, and a typical

output third-order intercept (OIP3) of 20 dBm at 27 GHz to 31 GHz,

requiring only 25 mA from a 2 V supply voltage. Note that the OIP3

can be improved with larger drain currents. The ADL8142-2C-CSL

also features inputs and outputs that are AC-coupled and internally

matched to 50 Ω, making it ideal for high capacity microwave radio

applications.
