Higher Input Power

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 or-

der 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-S-

9500, MIL-STD-202 and MIL-STD-750 which specify me-

chanical, electrical, thermal and other environmental tests

common to military semiconductor products.
