RFPA5542
WiFi Integrated PA Module
4.9GHz to 5.925GHz
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.

RFMD Green: RoHS status based on EU
Directive 2011/65/EU (at time of this
document revision), halogen free per IEC
61249-2-21, < 1000ppm each of
antimony trioxide in polymeric materials
and red phosphorus as a flame retardant,
and <2% antimony in solder.
Exceeding any one or a combination of the Absolute
Maximum Rating conditions may cause permanent
damage to the device. Extended application of Absolute
Maximum Rating conditions to the device may reduce
device reliability. Specified typical performance or
functional operation of the device under Absolute
Maximum Rating conditions is not implied. This is an
InGaP PA designed for high duty cycle applications with
Tj>30oC over ambient.
