General Description
The MAX3503 programmable power amplifier is
designed for use in CATV upstream applications. The
MAX3503 drives 61dBmV (QPSK) into a 75
load when
driven with a 34dBmV nominal input signal. Both input
nal balun be used at the output port. The variable gain
feature provides greater than 56dB of dynamic range,
which is controlled by an SPI 3-wire interface. Gain
control is available in 0.5dB steps. The device operates
over a frequency range of 5MHz to 65MHz. The
MAX3503 is internally matched for use with a 1:1 balun.
This device operates from a single 3.3V DC supply and
draws 235mA during transmit (100% duty cycle,
61dBmV out). The bias current is automatically
adjusted, based on the output level to increase efficien-
cy. Additionally, the device can be disabled between
bursts to minimize noise and save power while main-
taining a match at the output port. A shutdown mode is
available to disable all circuitry and reduce current con-
sumption to 5μA (typ).
The MAX3503 is available in a 20-pin QFN package.
The device operates in the extended industrial temper-
ature range (-40°C to +85°C).
