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 NESAT^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
• 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)
