Description
The AP157-317 is a linear, medium power amplifier
designed for low voltage operation. The device is
manufactured on our advanced InGap HBT process. It is
designed for use as the power amplifier in WLAN and other
2.42.5 GHz spread spectrum transmitters. The amplifier
is packaged in a 16 pin 4 x 4 mm micro lead package.
