Higher Input Power
• Lead-Free (RoHS* Compliant)
Description and Applications
The MA44600 series of Step Recovery diodes is de-
signed for use in low and moderate power multipliers
with output frequencies of up to 20 GHz. These Step
Recovery diodes generate harmonics by storing a
charge as the diode is driven to forward conductance
by the positive voltage of the input signal. When the
signal reverses polarity, this charge is extracted. The
Step Recovery diode will appear as a low impedance
current source until all the charge is extracted, then it
will “snap” to a higher impedance. This causes a volt-
age pulse to form in the impulse circuit of the multiplier.
Step Recovery diodes make excellent high order multi-
pliers such as comb generators. They are also useful
as efficient moderate power X2- X4 multipliers.
• High Order Narrow Band Moderate Power Multipliers
(MA44600 series)
• Comb Generators

Environmental Performance
The MA44600 and MA43000 series of diodes in ce-
ramic packages are capable of meeting the tests dic-
tated by the methods and procedures of the latest revi-
sions of MIL-S- 9500, MIL-STD-202 and MIL-STD-750
which specify mechanical, electrical, thermal and other
environmental tests common to military semiconductor
products.
