DESCRIPTION

The

µPC8126K is a silicon monolithic integrated circuit designed as quadrature modulator for digital mobile

communication systems. This IC integrates a pre-mixer for local signals plus a quadrature modulator operating from

889 MHz to 960 MHz. The chip which has been conventionally packaged in 20-pin SSOP is packaged in 28-pin QFN

and therefore is suitable for higher density mounting. In addition, the IC has power save function and can operate

2.7 to 3.6 V supply voltage. Consequently the

µPC8126K can contribute to make RF blocks smaller size, higher

performance and lower power consumption.

FEATURES

•

Directly modulate in 889 MHz to 960 MHz

•

•

External IF filter can be applied between modulator output and pre-mixer input terminal.

•

•

Equipped with power save function.

•

28-pin QFN suitable for higher density mounting.

APPLICATIONS

•

Digital cellular phones: PDC800M
