MACOM’s MHV-500 Series Microwave Hyperabrupt Tuning Varactors are silicon epitaxial mesa devices with high reliability glass passivation which ensures optimum VCO settling time and flat post tuning drift response. They offer Q values well above ion-implanted hyperabrupt diodes. These diodes offer octave tuning through 9 GHz. They are available in a wide variety of case styles for surface mount and/or cavity requirements. Chip devices are recommended for wide bandwidth performance and frequency response.
