| HMC774LC3B v00.0509 GaAs MMIC FUNDAMENTAL MIXER, 7 - 34 GHz Typical Applications The HMC774LC3B is ideal for: * Point-to-Point Radios * Point-to-Multi-Point Radios & VSAT * Test Equipment & Sensors Features Passive: No DC Bias Required Input IP3: +22 dBm LO/RF Isolation: 35 dB Wide IF Bandwidth: DC - 8 GHz 12 Lead Ceramic 3x3 mm SMT Package: 9mm2 9 MIXERS - SINGLE & DOUBLE BALANCED - SMT * Military End-Use 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.

Interface Schematic 9 MIXERS - SINGLE & DOUBLE BALANCED - SMT 2 LO This pin is DC coupled and matched to 50 Ohms. 4, 6, 11 N/C These pins are not connected internally; however, all data shown herein was measured with these pins connected to RF/DC ground externally. 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 or sink more than 2 mA of current or part non-function and possible part failure will result. 5 IF 8 RF This pin is DC coupled and matched to 50 Ohms. 9 - 396 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com HMC774LC3B v00.0509 GaAs MMIC FUNDAMENTAL MIXER, 7 - 34 GHz Evaluation PCB 9 MIXERS - SINGLE & DOUBLE BALANCED - SMT 9 - 397 List of Materials for Evaluation PCB 125042 [1] Item J1 - J2 J3 U1 PCB [2] Description Southwest K Connector Johnson SMA Connector HMC774LC3B Mixer 125040 Evaluation PCB [1] Reference this number when ordering compete evaluation PCB [2] Circuit Board Material: Arlon 25FR or Rogers 4350 The circuit board used in this application should use RF circuit design techniques. 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.
