X-Band FEM supports Phased Array Radar with High-Level Integration

Qorvo QPM2637, 9 to 10.5GHz, highly integrated FEM offers 36dBm output with 4W survivabilityRFMW, Ltd. announces design and sales support for high-performance, X-band front end modules. Designed for next-generation AESA radar applications, the Qorvo QPM2637 FEM incorporates a T/R switch, power amplifier, low noise amplifier and power limiter into a 6x6mm package. Saturated output power from the transmit amplifier is 36dBm with small signal gain of 32dB. Noise figure, on the receive side, is 2.7dB with small signal gain of 21dB. Built with field-proven GaN technology, the QPM2637 can withstand up to 4W of input power on the receive side without permanent damage, compared with a typical GaAs LNA, which can be damaged by less than 100mW. Operating in the 9 to 10.5GHz range, this GaN FEM solves many challenges associated with AESA radar system designs, including greater power output, higher efficiency, reliability, power and survivability, as well as savings in size, weight and cost.
