General Description
The HMC925LC5 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 16.5 dB with 30 dBc of sideband
rejection. The HMC925LC5 utilizes a RF amplifier
preceded by an I/Q mixer where the LO is driven
by a driver amplifier. 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 filtering of the unwanted
sideband. The HMC925LC5 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.
