Description and Applications
The MA44600 series of Step Recovery diodes is designed
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 voltage pulse to form in the impulse circuit of the
multiplier. Step Recovery diodes make excellent high order multipliers such as comb generators. They are also
useful as efficient moderate power X2- X4 multipliers.

Environmental Performance
The MA44600 and MA43000 series of diodes in ceramic
packages are capable of meeting the tests dictated by the
methods and procedures of the latest revisions of MIL-S9500, MIL-STD-202 and MIL-STD-750 which specify mechanical, electrical, thermal and other environmental tests
common to military semiconductor products.

Notes:
1.
When ordering, specify the desired case style by adding the case designation as a suffix to the model number. Case styles for the MA44600 series
are -30,-91 and –93. To order chip form, add the suffix “-134” to the model number. The nominal chip size for the MA44600 series is 15 mils.
2.
Reverse voltage (VR) is measured at a reverse bias current of 10µA.
3.
Junction capacitance is measured at a reverse voltage of 6V and a frequency of 1MHz.
4.
Transition time is measured between 20% and 80% points on the voltage recovery trace. Test conditions are +10mA and –10 volts.
