GENERAL DESCRIPTION
The AD61009 is a 3 V low power receiver IF subsystem for opera-
tion 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 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.
