General Description
The MAX3532 is a programmable power amplifier for use in upstream cable applications. The device outputs up to 62dBmV (continuous wave) through a 1:2 (voltage ratio) transformer when driven with 36dBmV at its input. It features variable gain, which is controlled via a 3-wire digital serial bus and available in 1dB steps. The operating frequency ranges from 5MHz to 42MHz.
