RF2424
UHF QUADRATURE MODULATOR
• Digital Communications Systems
• Spread Spectrum Communication Systems
• GMSK,QPSK,DQPSK,QAM Modulation
• GSM and D-AMPS Systems
• AM, SSB, DSB Modulation
• Image-Reject Upconverters
The RF2424 is a monolithic integrated quadrature modu-
lator IC capable of universal direct modulation for high-
frequency AM, PM, or compound carriers. Maximum out-
put power is +7.5 dBm, which is achieved with low input I
and Q signal levels. This low-cost IC implements differen-
tial amplifiers for the modulation inputs, 90° carrier phase
shift network, carrier limiting amplifiers, two matched dou-
ble-balanced mixers, summing amplifier, and an output
RF amplifier which will drive 50
Ω from 700MHz to
1000 MHz.
• Single 2.7V to 5.5V Power Supply
• +7.5dBm Output Power
• No Tuning Required
• Low LO Input Level
• Digitally Controlled Power Down Mode
• 700MHz to 1000MHz Operation
