The GRF2584 is a two-stage GaAs pHEMT low noise amplifier targeting high-performance wireless infrastructure applications. The device can be tuned to operate over narrow or wide bandwidths over a range of 3 to 9 GHz while delivering up to 36 dB of gain and noise figures as low as 1 dB.
For optimal efficiency and linearity, the amplifier was designed to operate with a single 5 V supply voltage while using only 50 mA of quiescent current. Supply voltages ranging from 2.7 to 6 V are also supported. Similarly, IDDQ can be increased beyond the native biasing point for enhanced linearity performance.
