IF LOW NOISE AMPLIFIER/MIXER
Product Description
The RF3334 is an IF LNA/Mixer suitable for downconver-
sion of forward channel control data in a set-top box appli-
cation. It consists of a single-ended 75惟 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 exter-
nal 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惟 load.
