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.

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.
