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 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 ADL8142S-CSL also features inputs and outputs that are accoupled and internally matched to 50 Ω, making it ideal for high capacity microwave radio applications.
