HMC774LC3B v00.0509 Mixers - SINGLE & DOUBLE BALANCED - SMT 10 GaAs MMIC Fundamental Mixer, 7 - 34 GHz Typical Applications Features The HMC774LC3B is ideal for: Passive: No DC Bias Required • Point-to-Point Radios Input IP3: +22 dBm • Point-to-Multi-Point Radios & VSAT LO/RF Isolation: 35 dB • Test Equipment & Sensors Wide IF Bandwidth: DC - 8 GHz • Military End-Use 12 Lead Ceramic 3x3 mm SMT Package: 9mm2 Functional Diagram General Description The HMC774LC3B 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 34 GHz. This mixer requires no external components or matching circuitry. The HMC774LC3B provides excellent LO to RF and LO to IF suppression due to optimized balun structures. The mixer operates best with LO drive levels above +15 dBm. The HMC774LC3B eliminates the need for wire bonding, allowing use of 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 Ohms.

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 board should be mounted to an appropriate heat sink. The evaluation circuit board shown is available from Hittite upon request.
