RoHs Compliant GaAs Hyperabrupt Varactor Diode Gamma= 1.0, 1.25 & 1.50 Features MA46410 thru MA46480 Series V4 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 ina 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. 1 M/A-COM Inc. and its affiliates reserve the right to make changes to the product(s) or information contained herein without notice.

Notes: 1. All GaAs tuning varactors are available in chip form as well as the case styles shown on the following page. When ordering, specify the desired case by adding the case designation as a suffix to the type number. 2. Case parasitics (Cp and Ls) are given for most case styles along with case outlines in the appendix. The Cp values listed typically have tolerances of ±0.02 pF. 3. The nominal tolerance at -4 Volts is ± 10%. Closer tolerances are available upon request. By adding the suffix A to the part number, a tolerance of ± 5% at -4 Volts is guaranteed. 4. 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). 5. Capacitance is measured at 1 MHz. 6. Reverse voltage (VB) is measured at 10 microamps. 7.
