5 High Q (up to 4000 at -4 Volts) Larger Capacitance Change with Voltage More Linear Frequency Tuning High and Nearly Constant Modulation Sensitivity Description The MA46450, MA46470 and MA46410 series of tuning varactors are hyperabrupt junction Gallium Arsenide diodes featuring constant gamma 1.
0 (MA46450 series), 1.
25 (MA46470 series) or 1.
5 (MA46410 series).
These diodes offer high Q (up to 4000) permitting excellent tuning performance from VHF through Ka band.
Each part in this series exhibits the large change in capacitance versus bias voltage characteristic of hyperabrupt junctions.
The standard capacitance tolerance is ±10%, with tighter tolerances available.
Capacitance matching at one or more bias voltages is also available.
All diode types are available in a wide selection of ceramic packages and in chip form.

5 available with these diodes enables the circuit designer to produce significant improvements in circuit performance.
Constant gamma tuning varactors permit more linear VCO frequency tuning than do conventional hyperabrupt tuning varactors.
These varactors are particularly well suited for use in voltage tuned filters, analog phase shifters, and modulator circuits.
