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.
