HMC924LC5
GaAs MMIC I/Q UPCONVERTER
10 - 16 GHz
v03.0312
General Description
FeaturesTypical Applications
The HMC924LC5 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 -30 dBc of sideband
rejection. The HMC924LC5 utilizes a RF amplier
preceded by an I/Q mixer where the LO is driven
by a driver amplier. IF1 and IF2 mixer inputs are
provided and an external 90° hybrid is needed to
select the required sideband. The I/Q mixer topology
reduces the need for ltering of the unwanted
sideband. The HMC924LC5 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.
