Description

The MA44600 series of Step Recovery diodes is designed

for use in low and moderate power multipliers with out-

put 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 imped-

ance. 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)

Notes:

1. When ordering, specify the desired case style by adding the case des-

ignation 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.
