DESCRIPTION

The µPC8104GR is a silicon monolithic integrated circuit designed as quadrature modulator for digital mobile communication systems. This modulator consists of 1.9 GHz up-converter and 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

• 20 pin SSOP suitable for high density surface mounting.

• High linearity up converter is incorporated; PRFout(sat)= −6 dBm TYP.

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

• Wide operating frequency range. Up converter; fRFout= 800 MHz to 1.9 GHz

Modulator ; 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.

• Supply voltage: VCC= 2.7 to 5.5 V

• Equipped with power save function.

APPLICATION

• Digital cordless phones

• Digital cellular phones
