Product Description
4
The RF2308 is a general purpose, low cost RF amplifier
IC. The device is manufactured on an advanced Gallium
Arsenide Heterojunction Bipolar Transistor (HBT) pro-
cess, and has been designed for use as an easily-cas-
cadable 50Ω gain block. Applications include IF and RF
amplification in wireless voice and data communication
products operating in frequency bands up to 4000MHz.
The device is self-contained with 50Ω input and output
impedances and requires only two external DC biasing
elements to operate as specified.
