Product Specification

PE4122

UltraCMOS™ High Linearity Quad

MOSFET Mixer For PCS & 3G BTS

Product Description

Features

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.

• Integrated, single-ended RF & LO

interfaces

• High linearity: IIP3 >+ 30 dBm,

1.8 - 2.0 GHz (+17 dBm LO)

• Low-conversion loss: 7.4 dB

(+17 dBm LO)

• High isolation: typical LO-IF at 38 dB,

LO-RF at 34 dB

• Designed for low-side LO injection

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.
