RFPA1545

4W P1dB, 5V Linear Power Amplifier

150MHz to 1000MHz

The RFPA1545 is a single-stage GaAs HBT power amplifier

specifically designed for high power, high efficiency applications.

It is also well-suited for Wireless infrastructure linear driver

amplifier applications. The RFPA1545 can be optimized for either

linear or saturated operation over sub-bands within 150MHz to

1000MHz. It also offers low noise figure making it an excellent

solution for 2nd and 3rd stage LNAs. The RFPA1545 exhibits

excellent thermal performance through the use of a thermally-

enhanced plastic surface-mount slug package.
