General Description

The HMC990LP4E is a high linearity, dual channel down-

converting mixer optimized for multi-standard diversity

receiver applications that require low power consump-

tion and small size. The HMC990LP4E features new

wideband limiting LO ampliﬁers to achieve an unprec-

edented RF bandwidth of 700 MHz to 3500 MHz. Unlike

conventional narrow-band downconverter RFICs, the

HMC990LP4E supports both high-side and low-side LO

injection over the entire RF frequency band. The RF and

LO input ports are internally matched to 50 Ω.

The HMC990LP4E integrates LO and IF ampliﬁers with

enable functions, LO and RF baluns and high linear-

ity passive mixer cores with bias control interface. The

balanced passive mixer combined with high-linearity IF

ampliﬁer architecture of HMC990LP4E provides excel-

lent LO-to-RF, LO-to-IF, and RF-to-IF isolations. The

HMC990LP4E provides a very low noise ﬁgure of 9 dB,

and high IIP3 of +25.6 dBm allowing device to be used in

demanding wideband applications. The HMC990LP4E’s

input IP3 can be further improved by external matching

for narrow-band applications. The HMC990LP4E has

typical less than 1.5 W power consumption which can

be optimized through external bias control pins. The

HMC990LP4E also features a very fast enable control

interface to be used for power saving in Time Division

Duplex (TDD) applications. The HMC990LP4E is housed

in a RoHS compliant 4x4 mm leadless QFN package.
