LNA with Selectable Gain
Tuning Range: 4.4 to 6 GHz
The GRF2583 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 27.2 and 15.2 dB, respectively.
For optimal efficiency and linearity, the amplifier was designed to operate with a single 5 V supply voltage while using only 52 mA of quiescent current. Supply voltages ranging from 2.7 to 6 volts are also supported. Similarly, quiescent current can be increased beyond the native biasing point for enhanced linearity performance.
