Product Description:
The TQP2420B is a linear, high performance, medium-power amplifier designed
for 802.11b WLAN and other applications in the 2.4GHz ISM band. The device
exhibits industry-leading power added efficiency under 802.11b CCK modulation
while meeting ACP requirements. The power amplifier is manufactured using
TriQuint's InGaP HBT process and is packaged in an industry standard 3mm x
3mm VQFN-12 package.
