Description Applications

M/A-COM offers four families of low cost surface

mount gallium arsenide tuning varactors. All fami-

lies have silicon nitride protected junctions for low

leakage current and high reliability.

The MA46H500 through MA46H504 family has

hyperabrupt junctions with constant gamma of 1.5

from 2 to 12 volts and high quality factor.

The MA46H200 through MA46H204 family has

hyperabrupt junctions with constant gamma of 1.25

from 2 to 20 volts and higher quality factor.

The MA46H070 through MA46H073 family has

hyperabrupt junctions with constant gamma of 0.75

from 0 to20 volts and very high quality factor.

The MA46504

through

MA46506

family has

abrupt junctions with constant gamma of 0.5 from 0

to 30 volts and the highest quality factor.

Applications

The MA46H500 through MA46H504 (gamma 1.5)

family of constant gamma hyperabrupt GaAs tuning

varactors is designed for wide bandwidth VCOs

and voltage tuned filters where limited bias voltage

is available. These varactors have

lower quality

factor than the other families of GaAs varactors.

The MA46H200 through M46H204 (gamma 1.25)

family of constant gamma hyperabrupt GaAs tuning

varactors has the largest capacitance ratio of the

families of GaAs varactors and high quality factor.

These diodes are very well suited for wide band-

width VCOs and VTFs where the optimum combi-

nation of very wide tuning range and high quality

factor is required.

Common Case styles

The MA46H070 through MA46H073 (gamma

0.75) family of constant gamma hyperabrupt GaAs

tuning varactors has quality factor approaching that

of abrupt junction varactors, but higher capacitance

change versus tuning voltage.These diodes are

very well suited for narrowerbandwidth VCOs and

VTFs where wide tuning range and very high qual-

ity factor are required.

The MA46504 through MA46506 (gamma 0.5)

family ofconstant gamma abrupt GaAs tuning

varactors has the highest quality factor. These di-

odes are very well suited for narrower bandwidth

VCOs and VTFs where highest quality factor is of

paramount concern.
