AD607ARSZ-REEL RF Mixer LINEAR IF SUB Up/Down Conv Mixer 3V 500MHz 20-Pin SSOP1500 X REEL ROHS5A991b.HTS: 542.39.0001GENERAL DESCRIPTION The AD607 is a 3 V low power receiver IF subsystem for operation at input frequencies as high as 500 MHz and IFs from 400 kHz to 12 MHz. It consists of a mixer, IF amplifiers, I and Q demodulators, a phase-locked quadrature oscillator, and a biasing system with external power-down.biasing system with external power-down. The AD607's low noise, high intercept mixer is a doubly balanced Gilbert cell type. It has a nominal -15 dBm input referred 1 dB compression point and a -8 dBm input referred third order intercept. The mixer section of the AD607 also includes a local oscillator (LO) preamplifier, which lowers the required LO drive to -16 dBm.In MGC operation, the AD607 accepts an external gain-control voltage input from an external AGC detector or a DAC.The I and Q demodulators provide in-phase and quadrature baseband outputs to interface with Analog Devices' AD7013 (IS54, TETRA, MSAT) and AD7015 (GSM) baseband converters. A quadrature VCO phase-locked to the IF drives the I and Q demodulators. The I and Q demodulators can also demodulate AM; when the AD607's quadrature VCO is phaselocked to the received signal, the in-phase demodulator becomes a synchronous product detector for AM. The VCO can also be phase-locked to an external beat-frequency oscillator (BFO), and the demodulator serves as a product detector for CW or SSB reception. Finally, the AD607 can be used to demodulate BPSK using an external Costas Loop for carrier recovery.DOWNLOAD DATASHEET
