RF9958

CDMA/FM TRANSMIT MODULATOR, IF AGC,

AND UPCONVERTER

• CDMA/FM Cellular Systems

• CDMA PCS Systems

• Wireless Local Loop Systems

• Spread Spectrum Cordless Phones

• High Speed Data Modems

• General Purpose Digital Transmitters

The RF9958 is an integrated complete Quadrature Modu-

lator, IF AGC amplifier, and Upconverter designed for the

transmit section of dual-mode CDMA/FM cellular and

PCS applications. It is designed to modulate baseband I

and Q signals, amplify the resulting IF signals while pro-

viding 95dB of gain control range, and perform the final

upconversion to UHF. Noise Figure, IP3, and other specifi-

cations are designed to be compatible with the IS-98

Interim Standard for CDMA cellular communications. This

circuit is designed as part of RFMD’s newest CDMA Chip

Set, which also includes the RF9957 CDMA/FM Receive

IF AGC and Demodulator. The IC is manufactured on an

advanced 15GHz FT Silicon Bipolar process, and is sup-

plied in a 28-lead plastic SSOP package.

• Supports Dual Mode Operation

• Digitally Controlled Power Down Modes

• 2.7V to 3.3V Operation

• Digital First LO Quadrature Divider

• Double-Balanced UHF Upconvert Mixer

• IF AGC Ampwith95dBGainControl
