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.
