Voltage Standing Wave Ratio (VSWR) is a fundamental parameter that measures the efficiency of radio frequency (RF) power transmission from a source through a transmission line to a load. A simple way to measure VSWR is to find the highest to lowest voltage ratio in a standing wave created on a transmission line due to […]
Achieving isolation in an isolation amplifier
Isolation amplifiers create a galvanic isolation barrier between input and output circuits to protect sensitive equipment and personnel from high voltages. Such isolation can be optical, capacitive, or inductive in an isolation amplifier. This FAQ will help us understand how each isolation type works and how they differ. How do optical isolation amplifiers work? Optical […]
What are the different encoding techniques used for chipless RFID tags?
Encoding refers to converting a message into a different transmission, storage, or processing form. Chipless RFID lacks specialized ASICs to lower costs and use time and frequency domain systems for encoding. Hybrid encoding combines time and frequency domain systems for custom encoding options. A chipless RFID system is a radio frequency identification technology that does […]
