RF9909 General Description

The RF9909 is a kind of complete AGC amplifier designed for the transmit section of dual-mode CDMA/FM cellular applications. It is intended to amplify IF signals while providing 84 dB of gain control range. Noise figure, IP3, and other specifications are designed to be compatible with the IS-95 interim standard for CDMA cellular communications. This circuit is designed as part of the RFMD CDMA chip set including a transmit IF AGC amp, a transmit upconverter, a receive LNA/Mixer, and this receive IF AGC amp. It is available in a standard miniature 16-lead plastic SSOP package.

There are some features as follows: (1)supports dual mode operation; (2)-45 dB to +39 dB gain control range; (3)single 3.6 V power supply; (4)monolithic construction; (5)DC to 200 MHz operation; (6)miniature surface mount package. The typical applications include: (1)CDMA/FM cellular systems; (2)supports dual-mode AMPS/CDMA; (3)supports dual-mode TACS/CDMA; (4)general purpose linear IF amplifier; (5)portable battery powered equipment.

The following is about the absolute maximum ratings: (1)supply voltage: -0.5 to 7.0 V; (2)RX/TX enable voltage: -0.5 to 5.0 V; (3)input RF power: +12 dBm; (4)operating ambient temperature: -40 to +85; (5)storage temperature: -40 to +150. Then is about the specifications about the power supply: (1)voltage: 3.6±5% V typ; (2)current consumption: 23 mA typ when maximum gain; (3)current consumption: 22 mA typ and 28 mA max when minimum gain.
