HMC258LC3B v02.1208 GaAs MMIC SUB-HARMONIC SMT MIXER, 14.5 - 19.5 GHz Typical Applications The HMC258LC3B is ideal for: • Point to Point Radios Features Integrated LO Amplifier: 0 dBm Input Sub-Harmonically Pumped (x2) LO High 2LO/RF Isolation: >45 dB Wide IF Bandwidth: DC - 3.5 GHz No External Matching Required RoHS Compliant 3x3mm Ceramic SMT Package 8 MIXERS - SUB-HARMONIC - SMT • VSAT and SATCOM • Test & Measurement Equipment • Military & Space Functional Diagram General Description The HMC258LC3B is a 14.5 - 19.5 GHz surface mount sub-harmonically pumped (x2) MMIC mixer with an integrated LO amplifier in a SMT leadless ceramic package. At 45 dB the 2LO to RF isolation eliminates the need for additional filtering. The LO amplifier is a single bias (+5V) two stage design with only 0 dBm drive requirement. The HMC258LC3B requires no external matching components, making it ideal for integrated subsystem applications. Utilizing the HMC258LC3B eliminates the need for wirebonding, thereby providing a consistent connection interface for the customer.

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.
