9 – 10.5 GHz GaN T/R Module: QPM2637
he QPM2637 is a Gallium Nitride MMIC front-end module (FEM) designed for X-Band radar applications within the 9-10.5 GHz range. The MMIC combines a T/R switch, low-noise amplifier, and a power amplifier. The receive path has dual-outputs which offer 21dB gain and 2.7dB noise figure. The transmit path delivers 4W of saturated power with 23dB large signal gain. The FEM is robust up to 4W of input power into the ANT port eliminating the need for a limiter.
The QPM2637 is fabricated on Qorvo's QGaN25 0.25um GaN-on-SiC process. The air-cavity EHS (embedded copper heat slug) surface mount package, coupled with a proprietary die-attach process, allows the QPM2637 to perform well at high case temperatures. Its compact size supports tight lattice spacing requirements needed for X-Band phased array radar applications.
