RF3322 General Description
The RF3322 is a variable gain amplifier for use in CATV reverse path (upstream) applications. It is DOCSIS-compliant for use in cable modems. The gain control covers a 58dB range and is serially programmable via three-wire digital bus for compatibility with standard baseband chips ets. Amplifier shutdown and transmit disable modes are software- and hardware-controlled. The device is placed into sleep mode via the serial control bus. The device operates over the frequency band of 5MHz to 65MHz for use in current U.S. and European systems. The amplifier delivers up to 60dBmV at the output of the balun. Gain is controllable in accurate 1dB steps. The device is provided in an industry-standard QSOP-20 package.

RF3374 General Description
The RF3374 is a general purpose, low-cost RF amplifier IC. The device is manufactured on an advanced Gallium Arsenide Heterojunction Bipolar Transistor (HBT) process, and has been designed for use as an easily-cascadable 50 gain block. Applications include IF and RF amplification in wireless voice and data communication products operating in frequency bands up to 6000MHz. The device is self-contained with 50 input and output impedances and requires only two external DC-biasing elements to operate as specified.
