PW0-105 · Question #93
Given: Return Loss is the decrease of forward energy in a system when some of the power is being reflected back toward the transmitter. What causes high return loss in an RF transmission system?
The correct answer is B. An impedance mismatch between devices in the RF system. See the full explanation below for the reasoning.

Options
- AA Voltage Standing Wave Ratio (VSWR) of 1:1
- BAn impedance mismatch between devices in the RF system
- CCross-polarization of the RF signal as it passes through the RF system
- DThe use of different connector types in the RF system (e.g. N-type and SMA-type)
- ELow output power at the transmitter and use of a high-gain antenna
