PRELIMINARY DATA SHEET
BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC8158K
RF UP-CONVERTER WITH AGC FUNCTION + IF QUADRATURE MODULATOR IC
FOR DIGITAL MOBILE COMMUNICATION SYSTEMS
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. 20 GHz fT silicon bipolar process NESATTM III to realize low power consumption. Consequently the
µPC8158K can contribute to make RF blocks smaller size, higher performance and lower power consumption.
FEATURES
• Supply voltage: VCC = 2.7 to 4.0 V, ICC = 28 mA @ VCC = 3.0 V
• 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
• Excellent performance: Padj = –65 dBc TYP. @ 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)
