HIGH IP3 RFIC DUAL

DOWNCONVERTER, 1.7 - 2.7 GHz

v04.1007

General Description

Features

Functional Diagram

The HMC381LP6 & HMC381LP6E are high linearity

Dual Down Converter Receiver ICs that operate

from 1.7 - 2.7 GHz and deliver a +27 dBm input third

order intercept point for UMTS, PHS and WiMAX

applications. The passive mixer outputs and high

dynamic range IF amplifier inputs are positioned

so that an external IF filter can be placed in series

between them. The converter provides a gain of

9 dB and 12 dB typical single side band noise

figure. The IC operates from a positive +5V rail

consuming 260 mA of current while requiring a LO

drive level of only -4 to +4 dBm. The design requires

no external baluns and supports IF frequencies

between 50 and 300 MHz.

Input IP3: +27 dBm

Low Single Input LO Drive: 0 dBm

Conversion Gain: 9 dB

Noise Figure: 12 dB

Single Positive Supply: +5V @ 260 mA

Typical Applications

The HMC381LP6 / HMC381LP6E is ideal for Wireless

Infrastructure Applications:

• GSM, GPRS & EDGE

• CDMA & W-CDMA

• PHS & PDC

• WiMAX
