Single Diode Configuration: MACOM offers four families of low cost surface mount gallium arsenide tuning varactors. All families have silicon nitride protected junctions for low leakage current and high reliability. The MA46H200 through MA46H204 family has hyper abrupt junctions with constant gamma of 1.25 from 2 to 20 volts and higher quality factor. The MA46H200 through M46H204 (gamma 1.25) family of constant gamma hyper abrupt 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.
