24 Lead Ceramic 4x4 SMT Package: 16mm2
General Description
The HMC620LC4 is a compact I/Q MMIC mixer in a
leadless “Pb free” RoHS compliant SMT package, which
can be used as either an Image Reject Mixer (IRM) or
a Single Sideband Upconverter. The mixer utilizes two
standard Hittite double balanced mixer cells and a 90
degree hybrid fabricated in a GaAs MESFET process. A
low frequency quadrature hybrid was used to produce a
100 MHz upper side band (USB) IF output. This product
is a much smaller and more consistent alternative
to hybrid style Image Reject Mixers and Single
Sideband Upconverter assemblies. The HMC620LC4
is compatible with high volume surface mount
manufacturing techniques.

Description
No connection required. These pins may be connected
to RF/DC ground without affecting performance.
These pins and package bottom must be connected
to RF/DC ground.
This pin is DC coupled
and matched to 50 Ohms.
This pin is DC coupled. For applications
9 IF1 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 IF
frequency range. For operation to DC, this pin must not
