High Gain Linear Driver
Tuning Range: 1.8 to 5 GHz

The GRF5126 is a high-gain, two-stage driver amplifier targeting 3.3 to 3.8 GHz wireless infrastructure applications. Custom tuning allows the device to work from 1.8 to 5 GHz. The device delivers 24.6 dBm of OP1dB, 31.1 dBm of OIP3 and a low Noise Figure (NF) of 1.9 dB. The device also provides two selectable gain modes allowing a single component to address multiple use cases.

For optimal efficiency and linearity, the amplifier was designed to operate with a single 5 V supply voltage while using only 85-100 mA of quiescent current. 3.3 V supplies can also be used while still yielding 21 dBm of OP1dB. If desired, I_DDQ can be increased beyond the native biasing point for enhanced linearity performance.

The GRF5126 is designed for 50 Ω systems, typically needing only a two-element shunt-series match on the input and output ports. Separate tunes allow the GRF5126 to maintain its excellent performance over bandwidths exceeding 400 MHz.
