GENERAL DESCRIPTION

The ADL8142 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 provides a typical gain of

27 dB, a 1.6 dB typical noise figure, and a typical output 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 ADL8142 also features

inputs and outputs that are ac-coupled and internally matched to

50 Ω, making it ideal for high capacity microwave radio applica-

tions.

The ADL8142 is housed in a RoHS-compliant, 2 mm × 2 mm,

8-lead LFCSP.
