QPF0219

RF Front End (LNA + PA) Overview

The QPF0219 is a multi-chip Front-End Module (FEM) designed for 2 GHz to 18 GHz wide-band radar applications. It integrates transmit/receive (T/R) switches, limiters, low-noise amplifiers (LNAs), and power amplifiers into a single unit. The module provides 13 dB large signal gain and 19 dB small signal gain. It delivers 10 W of output power and operates within an 8x8 mm air cavity QFN package.
