Upstream CATV Amplifier with On-Chip Anti-Alias Filter

General Description The MAX3507 is a variable-gain power amplifier for use in CATV upstream transmitters. The variable-gain feature has 55dB of dynamic range and is controlled by a 3-wire SPI? bus. The device is capable of generating +64dBmV output (16QAM/QPSK) when driven with a +34dBmV nominal
