PRELIMINARY DATA SHEET

DESCRIPTION

The

µPC8158K is a silicon microwave monolithic integrated circuit designed as quadrature modulator for digital

mobile communication systems. This MMIC consists of 0.8 GHz to 1.5 GHz up-converter and 100 MHz to 300 MHz

quadrature modulator which are equipped with AGC and power save functions.

This configuration suits to IF

modulation system. The package is 28-pin QFN suitable for high density mounting. The chip is manufactured using

NEC’s.

TM

III to realize low power consumption.

Consequently the

µPC8158K can contribute to make RF blocks smaller size, higher performance and lower power consumption.

FEATURES

•

•

Built-in LPF suppresses spurious multipled by TX local (LO1)

•

AGC amplifier is installed in local port of up converter: GCR = 35 dB MIN. @ fout = 1.5 GHz

•

∆f = ±50 kHz, EVM = 1.2 % rms TYP.

•

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

APPLICATIONS

•

Digital cellular phones (PDC800M, PDC1.5G and so on)
