The LT
5506 is a 40MHz to 500MHz monolithic integrated
quadrature demodulator with variable gain amplifier (VGA),
designed for low voltage operation. It supports standards
that use a linear modulation format. The chip consists of
a VGA, quadrature down-converting mixers and lowpass
noise filters. The LO port consists of a divide-by-two stage
and LO buffers. The IC provides all building blocks for IF
down-conversion to I and Q baseband signals with a single
supply voltage of 1.8V to 5.25V. The VGA gain has a linear-
in-dB relationship to the control input voltage. Hard-clip-
ping amplifiers at the mixer outputs reduce the recovery
time from a signal overload condition. The lowpass filters
reduce the out-of-band noise and spurious frequency
components. The cut-off frequency of the noise filters is
approximately 8.8MHz. The external 2xLO frequency is
required to be twice the IF input frequency for the mixers.
The standby mode provides reduced supply current and
fast transient response into the normal operating mode
when the I/Q outputs are AC-coupled to a baseband chip.
