Description
Data Sheet ADL8142 GaAs, pHEMT, MMIC, Low Noise Amplifier, 23 GHz to 31 GHz FEATURES ► Low noise figure: 1.6 dB typical at 27 GHz to 31 GHz ► Single positive supply (self biased) ► High gain: 27 dB typical at 27 GHz to 31 GHz ► High OIP3: 21.5 dBm typical at 27 GHz to 31 GHz ► RoHS-compliant, 2 mm × 2 mm, 8-lead LFCSP APPLICATIONS ► Satellite communication ► Telecommunications ► Civilian radar 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 applications. The ADL8142 is housed in a RoHS-compliant, 2 mm × 2 mm, 8-lead LFCSP. FUNCTIONAL BLOCK DIAGRAM Figure 1. Rev.
