RF2713
QUADRATURE MODULATOR/DEMODULATOR
The RF2713 is a monolithic integrated quadrature modulator/demodula-
tor. The demodulator is used to recover the I and Q baseband signals from
the amplified and filtered IF. Likewise, the inputs and outputs can be
reconfigured to modulate I/Q signals onto an RF carrier. The RF2713 is
intended for IF systems where the IF frequency ranges from 100kHz to
250MHz, and the LO frequency is two times the IF. The IC contains all of
the required components to implement the modulation/demodulation
function and contains a digital divider type 90° phase shifter, two double
balanced mixers, and baseband amplifiers designed to interface with Ana-
log to Digital Converters. The unit operates from a single 3V to 6V power
supply.
