HMC620LC4 v01.1007 MIXERS - SMT 8 GaAs MMIC I/Q MIXER 3 - 7 GHz Typical Applications Features The HMC620LC4 is ideal for: Wide IF Bandwidth: DC - 3.5 GHz • Point-to-Point High Image Rejection: 32 dB • Point-to-Multi-Point Radio High LO to RF Isolation: 43 dB • WiMAX & Fixed Wireless High Input IP3: +22 dBm • VSAT 24 Lead Ceramic 4x4 SMT Package: 16mm2 Functional Diagram 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. Electrical Specifi cations, TA = +25 °C, IF= 100 MHz, LO = +15 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 DC coupled and matched to 50 Ohms. 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 DC coupled and matched to 50 Ohms.
