General Description
The HMC6789BLC5A is a compact GaAs MMIC I/Q
downconverter in a 12-terminal, RoHS compliant,
ceramic leadless chip carrier (LCC) package. This
device provides a small signal conversion gain of 14 dB
with 25 dBc of image rejection. The HMC6789BLC5A
utilizes a low noise amplifier to drive the 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 HMC6789BLC5A is a much
smaller alternative to hybrid style single sideband
downconverter assemblies and it eliminates the need
for wire bonding by allowing the use of surface mount
manufacturing techniques.
