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.

Features
• Integrated, single-ended RF & LO interfaces
• High linearity: IIP3 > +32 dBm, 820 - 920 MHz (+17 dBm LO)
• Low conversion loss: 6.9 dB (+17 dBm LO)
• High isolation: typical LO-IF at 43 dB, LO-RF at 31 dB
• Designed for low-side LO injection
