The RF2312 is a general purpose, low cost high linearity
RF amplifier IC. The device is manufactured on an
advanced Gallium Arsenide Heterojunction Bipolar Tran-
sistor (HBT) process, and has been designed for use as
an easily cascadable 75Ω gain block. The gain flatness of
better than 0.5dB from 5MHz to 1000MHz, and the high
linearity, make this part ideal for cable TV applications.
Other applications include IF and RF amplification in
wireless voice and data communication products operat-
ing in frequency bands up to 2500MHz. The device is
self-contained with 75Ω input and output impedances,
and requires only two external DC biasing elements to
operate as specified.
