Product Description
The RF2480 is a monolithic integrated quadrature modulator IC capable
of universal direct modulation for high-frequency AM, PM, or compound
carriers. This low-cost IC features excellent linearity, noise floor, and
over-temperature carrier suppression performance. The device imple-
ments differential amplifiers for the modulation 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 is used to obtain
excellent amplitude balance and phase accuracy.

reduced appropriately. 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 modulation amplitude) should never exceed 4.0V. See pin 1
