The GRF2176 is a two-stage GaAs pHEMT low noise amplifier targeting high-performance wireless infrastructure applications. The second stage can be bypassed with an independent control pin, thus allowing the device to support high and low gain modes of 32.4 and 15.8 dB, respectively.
For optimal efficiency and linearity, the amplifier was designed to operate with a single 5 V supply voltage while using only 66 mA of quiescent current. Supply voltages ranging from 2.7 to 6 V are also supported. Similary, IDDQ can be increased beyong the native biasing point for enhanced linearity performance.
