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 se-
ries exhibits the large change in capacitance ver-
sus bias voltage characteristic of hyperabrupt junc-
tions. The standard capacitance tolerance is
±10%, with tighter tolerances available. Capaci-
tance 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 tun-
ing than do conventional hyperabrupt tuning varac-
tors.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 as well
as the case styles shown on the following page. When
ordering, specify the desired case by adding the case des-
ignation as a suffix to the type number.
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.
The nominal tolerance at -4 Volts is ± 10%. Closer toler-
ances are available upon request. By adding the suffix A to
the part number, a tolerance of ± 5% at -4 Volts is guaran-
teed.
The values guaranteed for gamma are measured on un-
packaged chips. The total capacitance versus bias voltage
curve will deviate slightly from the chip capacitance versus
bias voltage curve due to the package parasitic capaci-
tance (Cp).
Capacitance is measured at 1 MHz.
Reverse voltage (VB) is measured at 10 microamps.
The total capacitance and capacitance ratios shown are for
diodes housed in case style 30. Other case styles will re-
sult in different values.
