Product Description
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惟 termi-
nated 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 ampli-
fier 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惟 load.
