High Gain Linear Driver
Tuning Range: 1.8 to 5 GHz
The GRF5126 is a high-gain, two-stage driver amplifier targeting 1.8 to 5 GHz wireless infrastructure applications. The device delivers 24.5 dBm of OP1dB, 35 dBm of OIP3 and a low Noise Figure (NF) of 2 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, IDDQ 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.
