HMC553LC3B v00.1205 MIXERS - SMT 7 GaAs MMIC FUNDAMENTAL MIXER, 7 - 14 GHz Typical Applications Features The HMC553LC3B is ideal for: Passive Double Balanced Topology • Point-to-Point Radios High LO/RF Isolation: 50 dB • Point-to-Mulit-Point Radios Low Conversion Loss: 7 dB • Test Equipment & Sensors Wide IF Bandwidth: DC - 5 GHz • Military End-Use RoHS Compliant 3x3 mm SMT Package Functional Diagram General Description The HMC553LC3B is a general purpose double balanced mixer in a leadless RoHS compliant SMT package that can be used as an upconverter or downconverter between 7 and 14 GHz. This mixer is fabricated in a GaAs MESFET process, and requires no external components or matching circuitry. The HMC553LC3B provides excellent LO to RF and LO to IF isolation due to optimized balun structures and operates with LO drive levels as low as +9 dBm. The RoHS compliant HMC553LC3B 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 2 mA of current or part non-function and possible part failure will result. 8 RF This pin is DC coupled and matched to 50 Ohm from 7 to 14 GHz. 10, 11, 12 N/C No connection required. These pins may be connected to RF/DC ground without affecting performance.
