Impedance mismatches in a radio-frequency (RF) electrical transmission line cause power loss and reflected energy. Voltage standing wave ratio (VSWR) is a way to measure transmission line ...

Knowing the directivity specification of your measurement device can go a long way in setting measurement expectations. Directional power measurements are important when determining transmitter output ...

Co-sponsored by Analog Devices and Richardson RFPD. This webcast will provide a step-by-step approach to designing RF power and return loss measurement systems. The webcast will focus on a number of ...
