Product Description
The PE4122 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 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 PE4122 is optimized for frequency
down-conversion using low-side LO injection for PCS & 3G
Base Station applications, and is also suitable for use in
up-conversion applications.
The PE4122 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 260 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 ETK4-2T, nominal loss 0.7dB at 260 MHz).
*Test conditions unless otherwise noted: LO = 260 MHz, LO input drive = 17 dBm, RF input drive = 0 dBm.
