RF2713
QUADRATURE MODULATOR/DEMODULATOR
• Digital and Analog Receivers and
Transmitters
• High Data Rate Digital Communications
• Spread-Spectrum Communication Systems
• Interactive Cable Systems
• Portable Battery-Powered Equipment
The RF2713 is a monolithic integrated quadrature modu-
lator/demodulator. The demodulator is used to recover
the I and Q baseband signals from the amplified and fil-
tered IF. Likewise, the inputs and outputs can be reconfig-
ured to modulate I/Q signals onto an RF carrier. The
RF2713 is intended for IF systems where the IF fre-
quency ranges from 100kHz to 250MHz, and the LO fre-
quency 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 base-
band amplifiers designed to interface with Analog to Digi-
tal Converters. The unit operates from a single 3V to 6V
power supply.
