The RF2484 is a monolithic integrated quadrature modu-
lator 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-tem-
perature carrier suppression performance.
implements differential amplifiers for the modulation
inputs, 90° carrier phase shift network, carrier limiting
amplifiers, two matched double-balanced mixers, sum-
ming amplifier, and an output RF amplifier which will drive
50
from 800MHz to 2500MHz. It is packaged in a small
industry-standard LCC 16-pin plastic package.
The device
Typical Carrier Suppression>35dBc,
Sideband Suppression>35dBc over
temperature with highly linear operation
Noise Floor better than -152dBm/Hz
from 800MHz to 2200MHz
