Signing Out Cancel Continue as Guest Fairview Microwave's Reflection Attenuator Calculator allows you to determine the two possible resistor values (R1 > Z0 & R1 < Z0) for a reflection attenuator (measured in Ohms). Bookmark or "Favorite" this page by pressing CTRL + D. R1 > Z0: R1 < Z0: Reflection Attenuators use two equal resistors, each grounded and connected to the same node, to attenuate a signal. For this reason, there are two possible solutions to the value of the resistors used, one larger than the system impedance and one smaller. Visit Fairview Microwave's RF coaxial attenuators page for product details. **Note: All of our calculators allow SI prefix input. For example, if you wish to input "25000000", just type "25M" instead. See the quick-reference table below for all compatible SI prefixes.
