The MAX2472/MAX2473 are ideal replacements for dis-
crete solutions where a VCO output must drive more
than one input, especially where high reverse isolation
and low supply currents are mandatory. The MAX2472
features a two-stage wideband architecture with a high-
input-impedance common-emitter amplifier followed by
