The QPF4010 from Qorvo is a high-performance MMIC front-end module designed for the 5G phased array base stations and terminals that operate in the n258 band (26 GHz). Operating from 24.25 to 27.5 GHz, the device combines a low noise high linearity LNA, a low insertion-loss high-isolation TR switch, and a high-efficiency multi-stage PA. The receive path (LNA + TR SW) is designed to provide 13.5 dB of gain and a noise figure of 4.0 dB. The transmit path (PA + SW) provides 17 dB of small signal gain and saturated output power of 22.5 dBm. It can operate at an average power of 14 dBm with 4% of typical EVM at 64 QAM, 100MHz modulated signal.
The QPF4010 is available in a small 4 x 4 x 0.85mm overmold QFN surface-mount package, matched to 50 Ohm and has integrated DC blocking capacitors on all RF ports allowing for simple system integration. This FEM is ideal for satellite communications, point to point data links and 5G systems.
