Functional Block Diagram
Product Description
The RFS1003 power amplifier is a high-power, high-
performance GaAs MESFET IC designed for use in
transmit applications in the 5.1-5.9 GHz frequency
band. With a P1dB of 29 dBm, the device is ideal as a
final stage for wireless applications requiring high
transmit linearity. The input of the PA is matched to 50
ohms and the output can be easily matched for optimum
linearity and power performance at the desired
frequency of operation between 5.1 and 5.9 GHz.
