INTERNAL FEEDBACK RECEIVER BASED VSWR MEASUREMENT |
摘要 |
<p>A method and apparatus of internal measurement of voltage standing wave ratio in a transmitter includes providing power to hardware comprising the transmitter, transmitting a signal from the transmitter, sampling the signal in both a transmitted feedforward direction toward an antenna and a reflected direction from the antenna, and computing in a processor associated with the transmitter the voltage standing wave ratio on the basis of the feedforward and reflected sampled signals. A method of calculating a voltage standing wave ratio (VSWR) in a transmitter includes storing, in a memory associated with a processor associated with the transmitter, a captured feedforward signal from the transmitter to an antenna, storing, in the memory, a captured feedback signal reflected from the antenna, and calculating the VSWR in the processor on the basis of the stored transmitted and reflected signals.</p> |
