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.

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. The total capacitance and capacitance ratios shown are for diodes
