com Product Specification PE4125 Product Description The PE4125 is a high linearity, passive Quad MOSFET Mixer for GSM 800 & Cellular Base Station Receivers and exhibits 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 PE4125 is optimized for frequency down-conversion using high-side LO injection for GSM 800 & Cellular Base Station applications, and is also suitable for use in up-conversion applications.
The PE4125 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.

An IF frequency of 70 MHz is a nominal frequency.
The IF frequency can be specified by the user as long as the RF and LO frequencies are within the specified maximum and minimum.
