Product Description:
The TQP2420G is a high performance, high linearity, medium-power amplifier
designed for 802.11b/g WLAN and other applications in the 2.4GHz ISM band.
The device exhibits industry-leading power added efficiency under 802.11b and
802.11g modulated signals. The power amplifier is manufactured using
TriQuint’s InGaP HBT process and is packaged in an industry standard 3mm x
3mm VQFN-12 package.

Application Data
Source Load
External matching
•The 50 Ohm match of the input and
output ports of the TQP2420G is
completed by the addition of a small
number of external components. The
optimum impedance presented to the
respective ports is described in the Smith
Chart plot at the right.
•The impedance shown can be achieved
by a number of topologies. The preferred
topology selected for Triquint 242x
evaluation board is shown in the
schematic.
