RFSP2020

2.4–2.5 GHz Power Amplifier

Product Description

The RFSP2020 power amplifier is a high-

Applications

•

802.11b/g WLAN

performance GaAs HBT IC designed for use in

transmit applications in the 2.4-2.5 GHz frequency

band. With a P1dB of 25 dBm, the device is ideal

as a final stage for wireless LAN applications

requiring high transmit linearity. Designed with

advanced linearizing techniques, the device

achieves a specific error vector magnitude (EVM)

with lesser backoff than conventional PA designs.

The PA exhibits unparalleled linearity and

efficiency for both 802.11b- and 802.11g-based

WLAN systems. The on-chip detector is perfect

for systems where power sensing is necessary.

The part operates off a single +3.3V supply.
