Description
The MAVR-0447 series of Step Recovery diodes is
designed for use in low power multipliers with output
frequencies of up to 5 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 cur-
rentsource 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 gen-
erators. They are also useful as efficient moderate
power X2-X4 multipliers.
