_______________General Desc ription
The monolithic MAX2452 is a quadrature modulator
with supporting oscillator and divide-by-8 prescaler. It
operates from a single +3V supply and draws only
4.1mA. The modulator accepts differential I and Q
baseband signals with amplitudes up to 1.35Vp-p and
bandwidths up to 15MHz. It produces a differential out-
put up to 80MHz.
Pulling the CMOS-compatible ENABLE pin low reduces
the supply current to 2μA. To minimize spurious feed-
back, the MAX2452’s internal oscillator is set at twice
the IF via external tuning components. The oscillator
and associated phase shifters produce differential sig-
nals exhibiting low amplitude and phase imbalance,
yielding 42dB sideband rejection. The MAX2452 comes
in a 16-pin narrow SO package.
