The PE4126 is a high linearity, passive Quad MOSFET Mixer
for DCS 1800 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
PE4126 is optimized for frequency down-conversion using
low-side LO injection for DCS 1800 Base Station applications,
and is also suitable for use in up-conversion applications.
The PE4126 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
High Linearity Quad MOSFET Mixer

Notes: 1. An IF frequency of 250 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/ACom ETK4-2T - nominal loss 0.7 dB at 250 MHz.)
*Test conditions unless otherwise noted: LO = 250 MHz, LO input drive = 17 dBm, RF input drive = 3 dBm.
