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. 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 phase-locked 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.APPLICATIONS GSM, CDMA, TDMA, and TETRA Receivers Satellite Terminals Battery-Powered Communications Receivers
