Description
The MA44700 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.
1. Operation of this device above any one of these parameters
may cause permanent damage.
2. Please refer to application note M538 for surface mounting
instructions

Mounting Information
The illustration indicates the recommended
mounting
pad
configuration
for
the
SC-79, SOT-323 and SOD-323 packages. Solder
paste containing flux should be screened onto the
pads to a thickness of 0.005- 0.007 inches. The
plastic package is placed in position, firmly adhering
to the solder paste.
Permanent attachment is performed by a reflow
soldering procedure during which the tab
temperature does not exceed +275
°C
and the body
temperature does not exceed +250
°C,
for standard
models and +260
°C
for the RoHS compliant
devices.
Please refer to Application Note M538 for surface
mounting instructions.
