HMC581LP6 / 581LP6E
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
ampli er inputs are positioned so that an external IF
lter can be placed in series between them. The con-
verter provides a gain of 9 dB and typical single side
band noise gure 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.

Evaluation PCB
The circuit board used in the nal application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be con-
nected directly to the ground plane similar to that
shown. A sufficient number of via holes should be
used to connect the top and bottom ground planes.
The evaluation circuit board shown is available from
Hittite upon request.
