Description
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 tun-
ing 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 toler-
ances 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.
Applications
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 frequen-
cy tuning 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.
