HMC381LP6

HIGH IP3 RFIC DUAL

DOWNCONVERTER, 1.7 - 2.2 GHz

v01.0704

General Description

Features

Functional Diagram

The HMC381LP6 is a high linearity Dual Down

Converter Receiver IC that operates from 1.7 - 2.2

GHz and delivers a +27dBm input third order in-

tercept point for UMTS & PHS 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 typi-

cal single side band noise figure. The IC operates

from a positive +5V rail consuming 260 mA of cur-

rent 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.
