They are used with other test instruments for mak-ing fixed- and swept-frequency return loss (SWR)measurements over a wide range of radio frequen-cies. Return loss measurements are made to check the performance of systems, subsystems, and micro-wave components such as amplifiers, directional ...
Also interesting is that for this combination of load, transmission line, and frequency, at lengths below about 55 ft the total power loss is actually less than the "matched line" loss. That's a tough concept to grasp if you've always thought of "matched line loss" as being equivalent ...
Also, if inflation runs hotter than your 2% increase, you still lose purchasing power in retirement. For example, if you receive annuity payments with a 2% COLA, those annual increases would have been insufficient to keep up with realized inflation over the last 4-5 years. Due to the post-...

Return Loss and SWR both display the match of the system, but they show it in different ways.The return loss displays the ratio of reflected power to reference power in dB. The return loss view is usually preferred over the SWR linear scale, because is easier to compare a small and large...
can also be accomplished when using this meter as a field strength meter. Also, comparing antennas can be accomplished with this meter. It is designed to be used for base stations or mobile operations and can be permanently installed in the antenna system without any measurable loss of power....
Any radio amateur knows the importance of an accurate RF power meter. A wattmeter can be used to measure gain in amplifiers, bandwidth in filters, field strength from antennas, transmitter power, SWR, return loss and many other things. T... TS Oz - 《Elektor Electronics》 被引量: 0发表:...
The resonant frequency got shifted down to 847 MHz (marker M3) and SWR value at 868 MHz frequency now is 6.61:1. The power loss is around 50%. Figure 2-5 Resonant Frequency Shifting after Casing and in Hand Placing Note: Users developing a device which should be in use in a hand or...
