DESCRIPTION

The µPC8129GR is a silicon monolithic integrated circuit designed as indirect quadrature modulator for digital mobile communication systems. This modulator consists of 0.8 GHz to 1.9 GHz up-converter and 100 MHz to 400 MHz quadrature modulator which are packaged in 20 pin SSOP. The device has power save function and can operate 2.7 to 5.5 V supply voltage, therefore, it can contribute to make RF block small, high performance and low power consumption.

FEATURES

• High linearity up converter is incorporated; PRFout = –5 dBm TYP./@fRFout = 900 MHz

• Wide operating frequency range. Up converter; fRFout = 800 MHz to 1900 MHz

Modulator ; fLO1in = 200 MHz to 800 MHz

fMODout = 100 MHz to 400 MHz, fI/Q = DC to 10 MHz

• External IF filter can be applied between modulator output and up converter input terminal.

• Low phase difference due to digital phase shifter is adopted.

• Supply voltage: VCC = 2.7 to 5.5 V

• Equipped with power save function.

• 20 pin SSOP suitable for high density surface mounting.

APPLICATIONS

• Digital cellular phones (ex. GSM etc…)

• Digital cordless phones
