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
