HMC787LC3B v00.0110 Mixers - SINGLE & DOUBLE BALANCED - SMT 9 GaAs MMIC Fundamental Mixer, 3 - 10 GHz Typical Applications Features The HMC787LC3B is ideal for: Passive Double-Balanced Topology • WiMAX Infrastructure High LO/RF Isolation: 55 dB • Microwave Radio Low Conversion Loss: 9 dB • ISM & UWB Radios Wide IF Bandwidth: DC - 4 GHz • Test Equipment & Sensors No External Matching Required • Military End-Use 12 Lead 3x3 mm SMT Package: 9 mm2 Functional Diagram General Description The HMC787LC3B is a general purpose double balanced mixer in a leadless RoHS compliant SMT package that can be used as an upconverter or downconverter between 3 and 10 GHz. This mixer is fabricated in a GaAs MESFET process, and requires no external components or matching circuitry. The HMC787LC3B provides excellent LO to RF and LO to IF isolation due to optimized balun structures and operates with LO drive level of +17 dBm. The ceramic SMT package eliminates the need for wire bonding, and is compatible with high volume surface mount manufacturing techniques.

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 or sink more than 8 mA of current or part non-function and possible part failure will result. 8 RF This pin is DC coupled and matched to 50 Ohms. 10, 11, 12 N/C The pins are not connected internally; however, all data shown herein was measured with these pins connected to RF/DC ground externally.
