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

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
