Product Description
The RF2126 is a high-power, high-efficiency, linear ampli-
fier IC. The device is manufactured on an advanced Gal-
lium Arsenide Heterojunction Bipolar Transistor (HBT)
process and has been designed for use as the final RF
amplifier in 2.45 GHz ISM applications such as WLAN
and POS terminals. The part will also function as the final
stage in digital PCS phone transmitters requiring linear
amplification operating between 1800MHz and
2500MHz. The device is packaged in an 8-lead plastic
package with a backside ground. The device is self-con-
tained with the exception of the output matching network
and power supply feed line. It produces a typical output
power level of 1W.
