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 NEC's 20 GHz fT
silicon bipolar process NESATTM III to realize low power
consumption. Consequently the UPC8158K can contribute to
make RF blocks smaller size, higher performance and lower
power consumption.
