The quiescent (DC) operating supply current is 2 mA. The operating supply voltage is 3.3V typical. To the N1 and N2 control inputs as follows: However, a differential input works best. The product will work with both a differential input as The inputs are applied to the input SMA I/O. To avoid reflections it is recommended that the divider TheĮquivalent output impedance is 50 Ohm. The output driver is capable of sourcing and sinking 24 mA. Therefore AC coupling is used at the input. The input is biased by two 500 Ohm resistors connected to a 1.6V DC bias. For lower frequencies make sure that the slew rate is The minimum frequency that can be input is 500 Mhz and the maximum frequency is 6.0 Ghz. The frequency divider has a differential analog interface.

The name 'billboard' comes from the famous 'billboard chart ' which everybody knows. The calculator used for this function was from Le on the web. billboard.js is a re-usable, easy interface JavaScript chart library, based on D3.js. The results of the calculator are shown below: copy to clipboard) GENERAL PUBLIC LICENSE There is a pdf help file online take a look in the files section. Some features may not available with other OS (e.g. This program was created for educational purposes. The same function can be done using a calculator as mentioned above. Smith Chart Calculator DESCRIPTION A small tool which allows all basic smith chart actions. Fritz Dellsperger, Juerg Tschirren and Roger Wetzel of the Berne Institute of Engineering and Architecture. The Smith Chart program used here is a freeware program developed by Prof. Just input the value of s11 or the reflection coefficient and read the impedance at that point.The example below converts a s11 magnitude of 0.6966 and angle 176.2 to an equivalent impedance directly. Another way to do the conversion is to use the Smith Chart. Obviously the calculations involve complex numbers as the impedances and the reflection coefficient are all complex numbers. Here Z is the impedance corresponding to the reflection coefficient, Zo is the characteristic impedance, Γ is the reflection coefficient. The basic conversion algorithm is as follows: However, if these specialized programs are not available then a conversion between s11 can be carried out from the known ( measured) value of s11 using either the Smith Chart or by using a simple calculator for the conversion. It can be used as is in certain software programs to analyze the input characteristics of a 2 – port circuit. S11 is the input reflection coefficient expressed in terms of s – parameters.
