MA46 Series

The MA46H500 through MA46H504 (gamma 1.5) family of constant gamma hyperabrupt GaAs tuning varactors is designed for wide bandwidth VCOs and voltage tuned filters where limited bias voltage is  available. These var-actors have greatest capacitance change versus voltage atthe cost of slightly lower quality factor than the other families of GaAs varactors.

The MA46H200 through MA46H206 (gamma 1.25) family of constant gamma hyperabrupt GaAs tuning varactors has the largest capacitance ratio of the families of GaAs varactors and high quality factor. These diodes are very well suited for wide bandwidth VCOs and VTFs where the optimum combination of very wide tuning range and high quality factor is required.

The MA46H070 through MA46H073 (gamma 0.75)family of constant gamma hyperabrupt GaAs tuning varactors has quality factor approaching that of abrupt junction var-actors, but higher capacitance change versus tuning volt- age. These diodes are very well suited for narrower bandwidth VCOs and VTFs where wide tuning range and very high quality factor are required.

The MA46504 through MA46506 (gamma 0.5)family of constant gamma abrupt GaAs tuning varactors has the highest quality factor. These diodes are very well suited for narrower bandwidth VCOs and VTFs where highest quality factor is of paramount concern. 

M/A-COM offers four families of low cost surface mountgallium arsenide tuning varactors. All families have sili-con nitride protected junctions forlow leakage currentand high reliability.

The MA46H500 through MA46H504family has hyper-abrupt junctions withconstant gamma of 1.5 from 2 to 12volts and high quality factor.

The MA46H200 through MA46H206family has hyper-abrupt junctions with constant gamma of 1.25 from 2 to20 volts and higher quality factor.

The MA46H070 through MA46H073family has hyper-abrupt junctions withconstant gamma of 0.75 from 0 to20 volts and very high quality factor.

The MA46504 through MA46506family has abrupt junc-tions with constant gamma of 0.5 from 0 to 30 volts andthe highest quality factor.
