HIGH IP3 RFIC DUAL

DOWNCONVERTER, 800 - 960 MHz

v00.0806

General Description

Features

Functional Diagram

The HMC581LP6 & HMC581LP6E are high linear-

ity Dual Down Converter Receiver ICs that operate

from 800 - 960 MHz and deliver a +26 dBm input third

order intercept point for UMTS & GSM 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 con-

verter provides a gain of 9 dB and typical single side

band noise figure of 13 dB. The IC operates from a

single +5V supply consuming 260 mA of current while

requiring only 0 dBm LO drive. The design requires no

external baluns, no external matching and supports IF

frequencies between 50 and 300 MHz.
