multiplier devices: msd 700 series step recovery diodes description the micrometrics msd 700 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 stability, reliability and low leakage currents at high temperatures. diodes are available in various capaci- tance ranges for each of the 4 voltage ratings. these diodes represent the lowest transition times (snap time) available for each voltage rating. unless otherwise specified, capaci- tance will be within the range shown above 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. applications the msd 700 series step recovery diodes are used as harmonic genera- tors for all orders of multiplication, x 2 through x 20, for both narrow and wide bandwidths. applications include local oscillators, voltage controlled oscillators, frequency synthesizers and up con- verters. they are also used in comb generators to generate a broad frequency spectrum and in high speed pulse shaping circuits. 36 typical performance multiplier devices .1 +.5 +.3 0 -1 -3 -6 -10 -20 -40 -100 .2 .4 .6 1 2 4 6 10 20 40 100 capacitance (pf) square law a-mode step recovery applied voltage (v) 100 10 1.0 0.1 1.0 10 input frequency, (f) (ghz) minimum minority carrier lifetime, (ns) > 10 f in input high pass filter output matching section bias network impulse generator output filter output matching section idler circuit srd typical srd multiplier features ? wide selection of tightend capacitance ranges low transition times high efficiencies packaging chip, glass, ceramic, surface mount, beam lead micrometrics, inc. 136 harvey road, building c, londonderry, nh 03053 voice: 603-641-3800, fax: 603-641-3500, internet: www.micrometrics.com, e-mail: serv@micrometrics.com
