The QPF5012 from Qorvo is a Front-End Module (FEM) that operates from 8.5 to 10.5 GHz. It is a multi-die solution designed for X band systems and uses optimal semiconductor technologies for each functional block to enhance Tx/Rx performance in challenging radar applications. This front-end module integrates a GaN-on-SiC-based power amplifier and T/R switch, along with a GaAs-based low-noise amplifier and limiter. In the Tx chain, this module delivers a saturated output power of 10 W with a power-added efficiency of 40%, while in the Rx chain, it provides a gain of 23 dB with a noise figure of 2.2 dB.
The QPF5012 front-end module requires a DC supply of 22 V (Tx) and 1.8 V (Rx), and consumes 240 mA (Tx) and 90 mA (Rx) of current. This RoHS-compliant FEM is available in a compact, over-molded, plastic QFN package measuring 7.0 x 5.0 mm.
