MASW-000834 Minimum Required Reverse Bias Voltage
Minimum reverse bias voltage on a PIN diode based product varies with frequency of operation and inci-
dent power levels. As a rule of thumb, a designer can always use the magnitude of the peak RF voltage or
empirically locate lower bias values than the peak RF voltage magnitude. However, it has been shown that
lower DC voltages can be used depending on the RF environment in which a diode is placed. In the plot
below, the minimum required reverse voltage vs. frequency is shown for an incident RF power of 50 Watts.
This trend line will shift lower if the incident RF power is decreased. The biasing values have not been
verified through measurement at M/A-COM Technology Solutions. As a result, please use the data below
as a guide only for biasing requirements as this data is based solely on generic PIN diode equations.4
Please be cautious in that lower reverse bias levels can degrade isolation and distortion in a PIN diode
based product.
