General Description
The HMC6787ALC5A is a compact GaAs MMIC I/Q
variable gain upconverter in a leadless RoHS compliant
SMT package. This device provides a small signal con-
version gain of 11 dB with 17 dBc of sideband rejection,
and 13 dB of gain control. The HMC6787ALC5A utilizes
a RF variable gain amplifier preceded by an I/Q mixer
where the LO is driven by a X2 multiplier. 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 HMC6787ALC5A 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.
