MAVR-0447 Series Surface Mount Low Power Step Recovery Diodes Features Rev. V1 Absolute Maximum Ratings 1,2 @ TA=+25 °C (Unless Otherwise Noted) 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 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 currentsource 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. Parameter Absolute Maximum Operating Temperature -65 °C to +125 °C Storage Temperature -65 °C to +125 °C Reverse Voltage 30V Forward Bias Current 50 mA Power Dissipation 250 mW 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 Applications The MAVR-0447 series step recovery are useful for surface mount low power applications.
