High Gain Linear Driver

Tuning Range: 2.3 to 2.7 GHz

The GRF5226 is a high-gain, three-stage driver amplifier targeting 2.3 to 2.7 GHz wireless infrastructure applications. The device delivers up to 30.4 dBm of OP1dB, 35.3 dBm of OIP3, and a low noise figure (NF) of less than 4.1 dB over its targeted band of operation.

For optimal efficiency and linearity, the amplifier was designed to operate with a single 5 V supply voltage while using only 85-105 mA of quiescent current. 3.3 V supplies can also be used while still yielding 26.3 dBm of OP1dB. If desired, I_CCQ can be increased beyond the native biasing point for enhanced linearity performance.

The GRF5226 is designed for 50 Ω systems, typically needing only a two-element shunt-series match on the output port.
