Product Specification

PE4126

High Linearity Quad MOSFET Mixer

for DCS 1800 BTS

Product Description

Features

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.

• Integrated, single-ended RF & LO

interfaces

• High linearity: IIP3 of +32 dBm,

1700 - 1800 MHz (+17 dBm LO)

• Low conversion loss: 7.9 dB

(+17 dBm LO)

• High Isolation: typical LO-IF at 37 dB,

LO-RF at 38 dB (1.8 GHz)

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

CMOS.

• Designed for low-side LO injection

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.
