Upstream CATV Amplifier with

On-Chip Anti-Alias Filter

General Description

Features

The MAX3507 is a variable-gain power amplifier for use

in CATV upstream transmitters. The variable-gain fea-

ture 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 input signal. The on-chip anti-alias

lowpass filter with 75MHz cutoff frequency saves sys-

tem design cost and space. The optional positive slope

generator provides system design flexibility.

Transmit Band

The device operates from a single +5V supply and

draws 220mA nominal during transmit at max gain

(100% duty cycle). For burst-type transmissions, the

device is shut off between bursts to minimize noise and

save power while still maintaining a match at the output.

The device is optimized for high linearity with harmonic

levels below -55dBc.
