DESCRIPTION
The UPC8112T is a silicon Monolithic Microwave Integrated
Circuit which is manufactured using the NESAT III process.
The NESAT III process produces transistors with fT approach-
ing 20 GHz. This device consists of a double balance mixer, an
IF amplifier, and a LO buffer amplifier. The device was de-
signed to be used as the first down converter for GPS and
wirelesscommunicationssuchascellular,PCS,and900MHz
cordlessphones.Operatingona3voltsupply,thisICisideally
suited for hand held portable designs.
NEC's stringent quality assurance and test procedures as-
sure the highest reliability and performance.
