100mW SPREAD-SPECTRUM TRANSMITTER IC
Typical Applications
• Digital and Analog Communication Systems • GMSK, QPSK, DQPSK, QAM Modulation
• Spread-Spectrum Communication Systems • AM, SSB, DSB Modulation
• Portable Battery-Powered Equipment
Product Description
The RF2423 is a monolithic integrated transmitter IC
capable of universal direct modulation for UHF AM, PM,
or compound carriers. The transmitter may be used
stand-alone for applications requiring not more than
100mW output power, or may be used to drive a final
power amplifier. The maximum output level is 100mW,
and is adjustable over a 25dB range by a single positive
voltage. This low-cost IC implements differential amplifi-
ers for the modulation inputs, 90 degree carrier phase
shift network, carrier limiting amplifiers, two matched dou-
bly-balanced mixers, variable gain summing amplifier for
