MA46410-MA46485 GaAs Hyperabrupt Varactor Diode Gamma = 1.0, 1.25, & 1.50
The MA46450, MA46470 and MA46410 of tuning varactors are hyperabrupt junction Gallium Arsenide diodes featuring constant gamma 1.0 (MA46450),1.25 (MA46470) or 1.5 (MA46410). These diodes offer high Q (up to 4000) permitting excellent tuning performance from VHF through Ka band. Each part in this 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. The constant gamma value of 1.0, 1.25 or 1.5 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.
