The RF3334 is an IF LNA/Mixer suitable for downconversion of forward channel control data in a set-top box application. It consists of a single-ended 75 terminated LNA, followed by a differential gain control stage with 30dB of analog gain control and a double-balanced mixer. The mixer load is available via pins 10 and 11 should an external filter be required. The mixer output is connected to an IF amplifier that can be configured from 10dB to 40dB gain with an external resistor. The amplifier is capable of 6V pk-pk output into a 1k load.
