Product Description
The RF5373 is a linear driver/amplifier that meets the FCC and ETSI
requirements for operation in the 2.4GHz to 2.5GHz (IEEE802.11b/g/n
and BT Class 1) bands. Operating from a single 1.8V to 3.6V supply, the
amplifier will easily be incorporated into WLAN designs with minimal exter-
nal components. The device is manufactured on an advanced InGaP Gal-
lium Arsenide Heterojunction Bipolar Transistor (HBT) process. The device
is provided in a 2.2mmx2.2mmx0.6mm, 8-pin, QFN with a backside
ground.
