HMC819LC5
v04.0614
GaAs MMIC I/Q UPCONVERTER
17.6 - 23.7 GHz
General Description
FeaturesTypical Applications
The HMC819LC5 is a compact GaAs MMIC I/Q
upconverter in a leadless RoHS compliant SMT
package. This device provides a small signal con-
version gain of 15 dB with -35 dBc of sideband
rejection. The HMC819LC5 utilizes a driver ampli๎er
preceded by an I/Q mixer where the LO is driven by
an active x2 multiplier. IF1 and IF2 mixer inputs are
provided and an external 90ยฐ hybrid is needed to
select the required sideband. The I/Q mixer topology
reduces the need for ๎ltering of the unwanted
sideband. The HMC819LC5 is a much smaller
alternative to hybrid style single sideband upconverter
assemblies and it eliminates the need for wire
bonding by allowing the use of surface mount man-
ufacturing techniques.
