描述 Description

DESCRIPTION
NEC's UPC2757TB and UPC2758TB are silicon RFICs manufactured 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.FEATURES
