DESCRIPTION
The UPC2757T and UPC2758T are L-Band Frequency Con-
verters manufactured using the NESAT III MMIC process.
These products consist of a double balanced mixer, IF ampli-
fier and LO buffer amplifier. The UPC2757T is designed for
low power consumption while the UPC2758T is designed for
low distortion. Both devices operate on a 3 volt supply voltage
making them ideal for portable hand held cellular, GPS, PCN
and wireless LAN applications.
NEC's stringent quality assurance and test procedures en-
sure the highest reliability and performance.
