Tuning Varactors: MBT 4500 Series
The Massachusetts Bay Technologies MBT4500’s series Tuning Varactors are silicon abrupt junction devices. Each device has been designed to obtain the highest Q and lowest resistance possible in 45 volt tuning diodes. Each device in this series has a high density silicon dioxide passivation which results in exceptionally low leakage currents at higher temperatures.
The MBT4500 series of silicon tuning diodes are used for both narrow and wideband tuning. They are suited for frequency tuning applications through KU band. The MBT4500 series are used in phase shifters, voltage controlled oscillators and frequency synthesizers.
Standard capacitance tolerance is ±10%. Diodes can be optimized for custom electrical or mechanical specifications upon request.
