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 thermally-
enhanced plastic surface-mount slug package.
