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 UltraCMOSTM 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.

1. 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. 2. Conversion Loss includes loss of IF transformer (M/A COM ETC1-1-13, nominal loss 0.7dB at 70 MHz).
*Test conditions unless otherwise noted: IF = 70 MHz, LO input drive = 17 dBm, RF input drive = 3 dBm. Document No. 70-0044-05 www.psemi.com

Description
Absolute Maximum Ratings are those values listed in the above table. Exceeding these values may cause permanent device damage. Functional operation should be restricted to the limits in the DC Electrical Specifications table. Exposure to absolute maximum ratings for extended periods may affect device reliability. Electrostatic Discharge (ESD) Precautions When handling this UltraCMOSTM device, observe the same precautions that you would use with other ESD-sensitive devices. Although this device contains circuitry to protect it from damage due to ESD, precautions should be taken to avoid exceeding the rating specified. Latch-Up Avoidance
