Product Specification

PE4125

High Linearity Quad MOSFET Mixer

for GSM 800 & Cellular BTS

Product Description

Features

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

• Integrated, single-ended RF & LO

interfaces

• High linearity: IIP3 > +32 dBm,

820 - 920 MHz (+17 dBm LO)

• Low conversion loss: 6.9 dB

down-conversion using high-side LO injection for GSM 800 &

Cellular Base Station applications, and is also suitable for use

in up-conversion applications.

(+17 dBm LO)

• High isolation: typical LO-IF at 43 dB,

LO-RF at 31 dB

The PE4125 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.

• Designed for low-side LO injection

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 70 MHz).

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