Functional Diagram
The HMC525LC4 is ideal for:
Point-to-Point and Point-to-Multi-Point Radio
VSAT
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
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.
