Ultra-linear PA/Driver

Tuning Range: 0.4 – 3.8 GHz

GRF4205 is a high linearity PA /Linear Driver with high reverse isolation. It delivers excellent Gain, P1dB and IP3 over a wide range of frequencies with fractional bandwidths of roughly 3 to 5%. The device can be biased over a wide range of Vcc from 3.0 to 9.0 V and ICCQ is adjustable for optimal efficiency and linearity.

Consult with the GRF applications engineering team for custom tuning/evaluation board data and device s-parameters.
