General Description
B
SO
LE
The HMC908LC5 is a compact GaAs MCM I/Q
downconverter in a leadless RoHS compliant SMT
ceramic package. This device provides a small signal
conversion gain of 11 dB with a noise figure of 2.2 dB
and 25 dB of image rejection. The HMC908LC5
utilizes an LNA followed by an image reject mixer
which is driven by an LO buffer amplifier. The image
reject mixer eliminates the need for a filter following the
LNA, and removes thermal noise at the image frequency. I and Q mixer outputs are provided and
an external 90° hybrid is needed to select the
required sideband. The HMC908LC5 is a much
smaller alternative to hybrid style image reject mixer
downconverter assemblies, and it eliminates the need
for wire bonding by allowing the use of surface mount
manufacturing techniques.

This pin is DC coupled. For applications not requiring operation to DC, this port should be DC blocked
externally using a series capacitor whose value has
been chosen to pass the necessary frequency range.
For operation to DC, this pin must not sink / source more
than 3 mA of current or part non-function and possible
failure will result.
