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.
