DESCRIPTION
The UPC2743GS and UPC2744GS are Silicon Monolithic Integrated Circuits designed using the NESAT II MMIC process. These products consist of UHF and VHF double balanced mixers and local oscillators, an IF amplifier, an oscillator output buffer amplifier and a UHF/VHF switching circuit. These devices are ideal for TV and VCR tuners. NEC's stringent quality assurance and test procedures ensure the highest reliability and performance.
