Product Description
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 75Ωgain 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 operating in frequency bands up to 2500MHz. The device is
self-contained with 75Ωinput and output impedances, and requires only two external DC biasing elements to operate as specified.
