For example to conduct test channel device under DUT you can use module with two individual multiplexing banks. GHz x Multiplexer Back to Top. If this case check to make sure that the rise time specification of switch module less than highest harmonic needs be routed with minimum distortion. For this reason some portion of the signal propagating through transmission line reflected back from load | 8x1 multiplexer theory language:en

This also the capacitance that exists between two conductors DC resistance per unit length of RF transmission line dielectric conductance frequency radians Because ideal cable has no leakage its characteristic impedance can calculated using above formula all components system have matched minimize signal losses and reflections manufacturers specifically design their equipment either . For example to conduct test channel device under DUT you can use module with two individual multiplexing banks. The figure below displays rise time measurement for harmonic of square wave. By discussing two varying approaches to building x multiplexer the example Figures and will demonstrate why one preferable. Figure displays the maximum and minimum amplitudes of resultant signal which occurs when reflected wave phase deg out with input respectively

An example of this can be seen from the graph in Figure which shows insertion loss NI PXI at its bandwidth . Insertion Loss Significant power the signal occurs length of transmission line it made to propagate through greater than. Hence a GHz switch for example from Vendor may have completely different performance metrics than B. Crosstalk is defined as the magnitude of signal that coupled between circuits such separate multiplexer banks on RF module. Upon preliminary examination of the higher level specifications both modules it appears that latter would be more suitable has better bandwidth . VSWR is another way of measuring signal reflections

In such cases it is important to contact the vendor and obtain more complete specifications determine product suited for your application. RF systems make up the bulk of market and include most communications . Though it may seem that the second module is better suited for routing signals between and GHz insertion loss data collected displayed Figure indicates otherwise. Vpp. Because of their small wavelengths highfrequency signals travel through cables in waves. A GHz Sine Wave Propagating through m Coaxial Cable the case of Signal length is much larger almost than wavelength it. Back to Top. fel function for var rf null div return gc if document s h yle. le function SharedLogHelper . The first approach cascades two x multiplexers to build single . Every switch in the real world has some parasitic capacitance inductance resistance and conductance. GHz x multiplexer with characteristic impedance the switch from alternative PXI vendor
