GRF5509 is a high efficiency PA that delivers 4 Watts OP1dB with Psat approaching 5 W with Vcc at 5.0 V and a low Iccq of 125 mA. PAE at Psat is 58%.

The device can be tuned over a range of frequencies from around 700 MHz to 1000 MHz with typical fractional bandwidths of 3 to 5%.

For frequencies in the 400-700 MHz range, GRF5504 offers similar output power and efficiency with the same package and pinouts with 40 dB small-signal gain.

For frequencies in the 400-500 MHz range, GRF5504 offers high output power and slightly higher efficiency with the same package and pinouts.
