HMC525LC4
GaAs MMIC I/Q MIXER
4 - 8.5 GHz
Features
Wide IF Bandwidth: DC - 3.5 GHz
Image Rejection: 40 dB
LO to RF Isolation: 50 dB
High Input IP3: +23 dBm
RoHS Compliant 4 x 4 mm SMT Package
General Description
The HMC525LC4 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
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
USB IF output. This product is a much smaller
alternative to hybrid style Image Reject Mixers and
Single Sideband Upconverter assemblies. The
HMC525LC4 eliminates the need for wire bonding
allowing use of 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.
RF Port. This pin is AC coupled and matched to
50 Ohms from 4 to 8.5 GHz.
IF Port. 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 IF
frequency range. For operation to DC, this pin must not
source/sink more than 3mA of current or part non-func-
tion and possible part failure will result.
LO Port. This pin is AC coupled and matched to
50 Ohms from 4 to 8.5 GHz.
