Product Description
The PE4124 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 PE4124 is optimized for frequency down-
conversion using low-side LO injection for GSM 800 & Cellular
Base Station applications, and is also suitable for use in
up-conversion applications.
The PE4124 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.

Notes: 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 70MHz).
*Test conditions unless otherwise noted: LO = 70 MHz, LO input drive = 17 dBm, RF input drive = 3 dBm.
