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 AD61009’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 AD61009 also includes a local oscillator (LO) preamplifier, which lowers the required LO drive to –16 dBm. In MGC operation, the AD61009 accepts an external gain- control voltage input from an external AGC detector or a DAC. A quadrature VCO phase-locked to the IF drives the I and Q demodulators. The I and Q demodulators can also demodu- late AM; when the AD61009’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 AD61009 can be used to demodu- late BPSK using an external Costas Loop for carrier recovery. Monoceiver is a registered trademark of Analog Devices, Inc.
