Description
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.
Applications
High Order Narrow Band Moderate Power Multipliers
(MA44600 series)
Comb Generators (MA43592, MA43543)
High Power Circuit Tested Multiplier (MA43000 Series)
Surface Mount Low Power Multipliers (MA44700 Series)

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 in chip form, add the suffix “134” to
the model number. The nominal chip size for the MA44600 series is
15 mils.
Transition Time TS4
(ps)
2. Reverse voltage (VR) is measured at a reverse bias current of 10 µA.
3. Junction capacitance is measured at a reverse voltage of 6 volts and a
frequency of 1 MHz.
4. Transition time is measured between 20% and 80% points on the voltage recovery trace. Test conditions are +10 mA and -10 volts.

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-S19500, MIL-STD-202 and MIL-STD-750 which specify
mechanical, electrical, thermal and other environmental
tests common to military semiconductor products.
