GRF5236

The GRF5236 is a high-gain, three-stage driver amplifier targeting 3.3 to 4.2 GHz wireless infrastructure applications. The device delivers up to 30.2 dBm of OP1dB, 33.2 dBm of OIP3, and a low noise figure (NF) of less than 4.2 dB over its targeted band of operation. OP1dB can be tuned down to 3.1 GHz, but the high frequency of the rated operating range will degrade.

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, ICCQ can be increased beyond the native biasing point for enhanced linearity performance.

The GRF5236 is designed for 50 Ohm systems, typically needing only a two-element shunt-series match on the output port.
