The UPC2743GS and UPC2744GS are Silicon Monolithic
Integrated Circuits designed using the NESAT II MMIC pro-
cess. These products consist of UHF and VHF double bal-
anced 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 en-
sure the highest reliability and performance.
