Detailed Description
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
two separate open-collector output stages. The
MAX2473 features a two-stage wideband architecture
with a high-input-impedance common-emitter amplifier
followed by one open-collector output stage, with the
added feature of output power control. Using values for
RBIAS from 11k to 23k allows the output power of
the MAX2473 to range from -2dBm to -10dBm.
