Product Description
The RF2422 is a monolithic integrated quadrature modulator IC capable
of universal direct modulation for high-frequency AM, PM, or compound
carriers. This low-cost IC implements differential amplifiers for the modu-
lation inputs, 90° carrier phase shift network, carrier limiting amplifiers,
two matched double-balanced mixers, summing amplifier, and an output
RF amplifier which will drive 50 from 800MHz to 2500MHz. Component
matching, which can only be accomplished with monolithic construction,
is used to full advantage to obtain excellent amplitude balance and phase
accuracy.

Pin Function Description
Interface Schematic

I SIG
Baseband input to the I mixer. This pin is DC-coupled. Maximum output See pin 1.
power is obtained when the input signal has a peak to peak amplitude of
2V. The recommended DC level for this pin is 3.0V. The peak minimum
voltage on this pin (VREF - peak modulation amplitude) should never drop
below 2.0V. The peak maximum voltage on this pin (VREF + peak modula-
tion amplitude) should never exceed 4.0V.
