Return Loss is the decrease of forward energy in a system when some of the power is being reflected back toward the transmitter. What will cause high return loss in an RF transmission system…
The correct answer is D. An impedance mismatch between components in the RF system. See the full explanation below for the reasoning.
Question
Return Loss is the decrease of forward energy in a system when some of the power is being reflected back toward the transmitter. What will cause high return loss in an RF transmission system, including the radio, cables, connectors and antenna?
Options
- AThe use of cables longer than one meter in the RF system
- BHigh output power at the transmitter and use of a low-gain antenna
- CA Voltage Standing Wave Ratio (VSWR) of 1:1
- DAn impedance mismatch between components in the RF system
