PE4126

www.DataSheet4U.com Product Specification PE4126 Product Description The PE4126 is a high linearity, passive Quad MOSFET Mixer for DCS 1800 Base Station Receivers exhibiting high dynamic range performance over a broad LO drive range up to 20 dBm. This mixer integrates passive matching networks to provide single-ended interfaces for the RF and LO ports, eliminating the need for external RF baluns or matching networks. The PE4126 is optimized for frequency down-conversion using low-side LO injection for DCS 1800 Base Station applications, and is also suitable for use in up-conversion applications. The PE4126 is manufactured on Peregrine’s UltraCMOS™ process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS.
