The QPM5811 is a GaAs MMIC front-end module (FEM) designed for X-Band radar applications within the 8.5 – 10.5 GHz range. The MMIC combines a T/R switch, low-noise amplifier, and a power amplifier. The receive path offers 26 dB gain with low noise figure of 2.0 dB. The transmit path offers a small signal gain of 30 dB, it can deliver 0.5 W of saturated power with a PAE of 45 %, with a 23.5 dB of large signal gain.
The 6 x 6 mm QFN surface mount package with over-mold encapsulant, coupled with high thermal conductivity die-attach process, allows the QPM5811 to perform well in a high temperature environment. Its compact size supports tight lattice spacing requirements needed for X-Band phased array radar applications.
