• High and Nearly Constant Modulation Sensitivity
• Lead-Free (RoHs Compliant) equivalents avail-
able with 260°C reflow compatibility.
Description and Applications
The MA46450, MA46470 and MA46410 series of tun-
ing varactors are hyperabrupt junction Gallium Ar-
senide diodes featuring constant gamma 1.0 (MA46450
series),1.25 (MA46470 series) or 1.5 (MA46410 se-
ries). These diodes offer high Q (up to 4000) permit-
ting 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 pro-
duce significant improvements in circuit performance.
Constant gamma tuning varactors permit more linear
VCO frequency tuning than do conventional hy-
perabrupt tuning varactors.These varactors are particu-
larly well suited for use in voltage tuned filters, analog
phase shifters, and modulator circuits.
