RFPA5542

General Description:

The RFPA5542 is a three-stage power amplifier (PA) designed for
802.11a/n/ac applications. The integrated input and output 50Ω match
greatly reduces the layout area, bill of materials and manufacturability
cost in the customer application. The PA is optimized to minimize the
required external components to maintain linear performance. The
RFPA5542 is manufactured on an advanced InGaP heterojunction bipolar
transistor (HBT) process and is capable of achieving linear powers up to
23dBm with an EVM <1.8% while maintaining excellent power added
efficiency. The device is provided in a 4.0mm x 4.0mm x 0.90mm
package that meets or exceeds the power requirements of
IEEE802.11a/n/ac WiFi RF systems.
