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
amplifi er inputs are positioned so that an external
IF fi lter can be placed in series between them. The
converter provides a gain of 9 dB and 12 dB typi-
cal single side band noise fi gure. 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.
