HMC523LC4 v00.0405 MIXERS - SMT 7 GaAs MMIC I/Q MIXER 15 - 23 GHz Typical Applications Features The HMC523LC4 is ideal for: Wide IF Bandwidth: DC - 3.5 GHz • Point-to-Point Radios Image Rejection: 25 dB • Point-to-Mulit-Point Radios & VSAT LO to RF Isolation: 47 dB • Test Equipment & Sensors High Input IP3: +25 dBm • Military End-Use RoHS Compliant 4x4 mm SMT Package Functional Diagram General Description The HMC523LC4 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 HMC523LC4 eliminates the need for wire bonding allowing use of surface mount manufacturing techniques. Electrical Specifications, TA = +25° C, IF= 100 MHz, LO = +17 dBm* Parameter Min.

These pins may be connected to RF/DC ground without affecting performance. 3, 5, 12, 14, 16 GND These pins and package bottom must be connected to RF/DC ground. 4 RF This pin is AC coupled and matched to 50 Ohms from 15 to 23 GHz. 9 IF1 11 IF2 15 LO Interface Schematic 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. This pin is AC coupled and matched to 50 Ohms from 15 to 23 GHz.
