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

• Current consumption ICC = 35 mA TYP. @ VCC = 3.0 V
• Equipped with power save function.
• 28-pin QFN suitable for higher density mounting.

APPLICATIONS
• Digital cellular phones: PDC800M
