The PE4135 is a high linearity passive Quad MOSFET Mixer

for GSM800 & Cellular Base Station Receivers, exhibiting high

dynamic range performance over a broad LO drive range of 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 PE4135 is optimized for frequency down-

conversion using low-side LO injection for GSM800 & Cellular

Base Station application, and is also suitable for up-conversion

applications.

The PE4135 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. Test conditions unless otherwise noted: IF = 70 MHz, LO input drive = 17 dBm, RF input drive = 3 dBm.

2. 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.

3. Conversion Loss includes loss of IF transformer (M/A COM ETC1-1-13, nominal loss 0.7 dB at 70 MHz).
