RFPA1545
4W P1dB, 5V Linear Power Amplifier 150MHz to 1000MHz
RFPA1545
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 thermallyenhanced plastic surface-mount slug package.
