Functional Diagram
The HMC528LC4 is ideal for:
• Point-to-Point Radios
• Point-to-Multi-Point Radios & VSAT
• Test Equipment & Sensors
• Military End-Use
Wide IF Bandwidth: DC - 3.5 GHz
Image Rejection: 35 dB
LO to RF Isolation: 45 dB
High Input IP3: +26 dBm
24 Lead 4x4mm SMT Package: 16mm²
The HMC528LC4 is a compact general purpose
I/Q MMIC mixer in a leadless 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 HMC528LC4 eliminates
the need for wire bonding allowing 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 IF
frequency range. For operation to DC, this pin must not
source/sink more than 3mA of current or part non-function
and possible part failure will result.

Evaluation PCB
The circuit board used in the application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground
leads and exposed paddle should be connected
directly to the ground plane similar to that shown.
A sufficient number of via holes should be used to
connect the top and bottom ground planes. The
evaluation circuit board shown is available from Hit-
tite upon request.
