Product Description
The PE4123 is a high linearity, passive Quad MOSFET Mixer for PCS & 3G Base Station Receivers, exhibiting high dynamic range performance over a broad LO drive range of 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 PE4123 is optimized for frequency down-conversion using high-side LO injection for PCS & 3G Base Station applications, and is also suitable for up-conversion applications.
