DESCRIPTION
The UPC8158K is a silicon microwave monolithic integrated circuit designed as a quadrature modulator for digital mobile communication systems. This MMIC consist of a 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 IF modulation systems and is packaged in a 28-pin QFN suitable for high density mounting. The chip is manufactured using NECs 20 GHz fT silicon bipolar process NESATTMIII to realize low power consumption. Consequently the UPC8158K 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 INSTALLED IN LOCAL PORT OF UPCONVERTER: GCR = 35 dB MIN. @ fout = 1.5 GHz
• EXCELLENT PERFORMANCE: Padj = -65dBc TYP. @ ∆f = ±50 KHz, EVM = 1.2 %rms TYP.
• EXTERNAL IF FILTER: Can be applied between modulator output and up converter input terminal

APLICATIONS
• Digital cellular phones (PDC800M, PDC1.5G,TDMA1900 and so on)
• Wireless Communiaction Systems (MMDS, Broadband wireless access)
