HMC264LC3B v01.0905 MIXERS - SMT 7 GaAs MMIC SUB-HARMONIC SMT MIXER, 21 - 31 GHz Typical Applications Features The HMC264LC3B is ideal for: Integrated LO Amplifier: -4 to +4 dBm Input • Point-to-Point Radios Sub-Harmonically Pumped (x2) LO • Point-to-Multi-Point Radios & VSAT High 2LO/RF Isolation: 30 dB • Test Equipment & Sensors DC - 6 GHz Wideband IF • Military End-Use RoHS Compliant 3x3 mm SMT Package Functional Diagram General Description The HMC264LC3B is a 21 - 31 GHz Sub-harmonically Pumped (x2) MMIC Mixer with an integrated LO amplifier in a leadless “Pb Free” SMT package. The 2LO to RF isolation is excellent at 30 dB, eliminating the need for additional filtering. The LO amplifier is a single bias (+3V to +4V) design with only -4 to +4 dBm drive requirement. The RF and LO ports are DC blocked and matched to 50 Ohms for ease of use while the IF covers DC to 6 GHz. The HMC264LC3B eliminates the need for wire bonding, allowing use of surface mount manufacturing 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.
