High Performance Broadband Mixers
API mixers use high-performance monolithic diodes for superior isolation and the lowest loss possible. They have synthesised input and output matching networks which maintain maximum response flatness across the performance band.In order to protect against corrosion and oxidation in extreme environments, hermetic sealing in Nitrogen is an option on select Kovar packages.
API mixers also uses duroid construction for reliable performance against thermal dynamics and shock, and strict attention to the IF quadrature yields superior image suppression. API Technologies keeps SSB noise low through the use of carefully selected diode bridge quads for low RD. Quarter wavelength stubs are used to provide diode ground paths and optimize Return Loss. We achieve superior high image suppression by maintaining a true 90° phase split with minimal loss.
API Technologies’ hybrid mixer product line (formerly Magnum Microwave) covers frequency ranges from 0.5 MHz to 26.5 GHz, in both double or triple balanced configurations. Available in many industry-standard surface mount, drop-in and connectorized housings:
