40MHz to 500MHz

Quadrature Demodulator

with VGA

FEATURES

DESCRIPTIO

TheLT^®5506isa40MHzto500MHzmonolithicintegrated

quadraturedemodulatorwithvariablegainamplifier(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-conversionto IandQbasebandsignalswithasingle

supplyvoltageof1.8Vto5.25V. TheVGAgainhasalinear-

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.
