POWER GENERATION
Step Recovery Diodes
RoHS Compliant
DESCRIPTION
The GC2500 series step recovery diodes are epitaxial silicon varactors which
provide high output power and efficiencies in harmonic generator
applications. Strict material and process controls result in high reproducibility.
A unique silicon dioxide passivation process assures greater reliability and
low leakage currents at high temperatures.
Diodes are available in various capacitance ranges for each of the 4 voltage
ratings. These diodes represent the lowest transition time (snap time)
available for each voltage rating. Unless otherwise specified, capacitance will
be within the range shown below for each type. A capacitance tolerance of
±10% is available at an additional charge. Diodes can be optimized for
custom electrical or mechanical specifications. Custom parameters for
capacitance, voltage, transition time, series resistance, etc. are available
upon request. All specifications shown above are based on the style 30
package. Many packages options are available, including 150A, 35, 36, 42
and 56. Chip mounted on carriers with gold wire/ribbon leads are also
available. Other package styles are available to meet specific requirements.
Some limitations apply. Contact Microsemi for details.

APPLICATIONS
The GC2500 series of step recovery varactors are used as harmonic
generators for all orders of multiplication X2 through X20 for both
narrow and wide bandwidths. Applications include local oscillators,
voltage controlled oscillators, frequency synthesizers, and up
converters. They are also used in comb generators to generate a
broad frequency spectrum and in high speed pulse shaping circuits.

Notes:
Junction capacitance is measure at 1 MHz.
Carrier lifetime is measure at I
F
= 10mA, I
R
= 6mA .
Series resistance is measure using a transmission loss technique @ 1 GHz.
Thermal resistance is measure using pulsed conditions while measuring forward voltage drop
across the diode mounted in an infinite heat sink.
