NEC's UPC2757TB and UPC2758TB are silicon RFICs manu-
factured using the NESAT™III process. The devices consist of
a mixer, an IF amplifier and an LO buffer amplifier. These
devices are suitable as 1st IF downconverters for the receiver
stage of cellular and other wireless systems. The UPC2757TB
is designed for low power consumption while the UPC2758TB
is designed for low distortion. The UPC2757TB/58TB are pin
compatible and have comparable performance to the larger
UPC2757T/58T, so they are suitable for use as a replacement
to help reduce system size. The IC is housed in a 6 pin super
minimold or SOT-363 package.
NEC's stringent quality assurance and test procedures ensure
the highest reliability and performance.
