GENERAL DESCRIPTION

The ADL8142S-CSL is a gallium arsenide (GaAs), monolithic mi-

crowave integrated circuit (MMIC), pseudomorphic high electron

mobility transistor (pHEMT), low noise wideband amplifier that

operates from 23 GHz to 31 GHz. The ADL8142S-CSL provides a

typical gain of 27 dB, a 1.6 dB typical noise figure, and a typical out-

put third-order intercept (OIP3) of 21.5 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 ADL8142S-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.

The ADL8142S-CSL is housed in a RoHS-compliant, 2 mm × 2

mm, 8-lead LFCSP. Additional application and technical information

can be found in the Commercial Space Products Program brochure

and the ADL8142 data sheet.
