MA144769-287 & MAVR-044769-1279 Surface Mount Low Power Step Recovery Diodes Rev. V3 Features SOT-23 (Case Style 287) Surface Mount Packages (SOT-23,SC-79) Low Transition Times SPC Process for Superior C-V Repeatability Tape and Reel Packaging Designed for Commercial Wireless Applications RoHS Compliant Description The MA144769-287 and the MAVR-044769-1279 step recovery diodes are 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 SC-79 (Case Style 1279) to forward conductance by the positive voltage of the input signal. When the signal reverses polarity, this charge is extracted. These diodes will appear as a low impedance current source 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 generators. They are also useful as efficient moderate power x2 - x4 multipliers. These step recovery diodes are useful for surface mount low power applications.
