Overview
19-2092; Rev 0; 7/01 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 input signal.
The on-chip anti-alias lowpass filter with 75MHz cutoff frequency saves system design cost and space.
The optional positive slope generator provides system design flexibility.
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.
The MAX3507 is available in a 28-pin QFN package and operates over the extended industrial tem...
