MA46410 thru MA46480 Series GaAs Hyperabrupt Varactor Diode Gamma = 1.0, 1.25, & 1.50 Features • • • • • Rev. V8 Common Case styles Constant Gamma = 1.0, 1.25 or 1.5 High Q (up to 4000 at -4 Volts) More Linear Frequency Tuning High and Nearly Constant Modulation Sensitivity Lead-Free (RoHs Compliant) equivalents available with 260°C reflow compatibility. Description and Applications 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. 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.

All GaAs tuning varactors are available in chip form . Please contact factory for part number information. Case parasitics (Cp and Ls) are given for most case styles along with case outlines in the appendix. The nominal tolerance at -4 Volts is ± 10%. Closer tolerances are available upon request. The values guaranteed for gamma are measured on unpackaged chips. The total capacitance versus bias voltage curve will deviate slightly from the chip capacitance versus bias voltage curve due to the package parasitic capacitance (Cp). Capacitance is measured at 1 MHz. Reverse voltage (Vbr) is measured at 10 microamps. The total capacitance and capacitance ratios shown are for diodes housed in case style 30 with Cp= 0.170pF unless otherwise specified. Other case styles will result in different values. Part only offered in die form. The capacitance values are for die form.
