QPF0219 is a multi-chip Front-End Module (FEM) designed for 2-18 GHz Wide-Band radar applications. The FEM integrates a T/R switch, a limiter, a low-noise amplifier and a power amplifier. Transmit power is 10 W saturated with 20% PAE and large signal gain is 13 dB, small signl is 19dB. The receiver noise figure is 4 dB, small signal gain is 14 dB, P1dB is 21 dBm.
The multi-die FEM offers the optimal semiconductor technology for each functional block to maximize performance in challenging radar applications. Power amplifier and T/R switch are GaN-on-SiC while limiter and LNA are GaAs.
Package is a 8 x 8 mm air cavity QFN. QPF0219 offers exceptional performance in a compact footprint.
