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) & 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 & 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.

2. All GaAs tuning varactors are available in chip form. Please contact factory for part number information.
3. 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).
4. Case parasitics (Cp and Ls) are given for most case styles along with case outlines in the appendix.
5. Closer tolerances are available upon request.
6. Reverse voltage (Vbr) is measured at 10 microamps.
7. The total capacitance and capacitance ratios shown are for diodes housed in case style 30 with Cp= 0.170 pF unless otherwise specified.
Other case styles will result in different values.
8. This part is offered in die form, shipped in a gel pack. The part number is MAVR-046479-01340G.
