Preliminary RF2721 QUADRATURE DEMODULATOR 2 Typical Applications • UHF Digital and Analog Receivers • Digital Communication Systems • Commercial and Consumer Systems • Portable Battery-Powered Equipment • Spread-Spectrum Communication Systems • General Purpose Frequency Conversion Product Description The RF2721 is a monolithic integrated quadrature demodulator intended for use in digital mobile radio receivers. In this application it is used to recover the inphase and quadrature baseband signals from the amplified and filtered IF. The RF2721 is intended for IF systems where the IF frequency ranges from 100kHz to 500MHz, and the LO frequency is two times the IF.
