CAN ANYBODY PLEASE GIVE AN EXAMPLE OF A U.H.F. CONNECTOR????Also kindly advise me on how can I reduce impedance losses while connecting a coaxial cable between a source and a load through connectors. Like a 50 MHz source and 50 MHz load impedance matching might suffer losses due to dielectrics(male-female air gap), resistance, etc.PLEASE PLEASE DO ANSWER.I URGENTLY NEED THE ANSWER.LOTS OF THANX IN ADVANCE
Type N connector is one of the best, good to 11 GHz, so it will handle 440 MHz with no problems. For 50 MHz, most any coax connecter will be fine. At 440 MHz, you have to be a bit more picky, but most good ones will work well. The second reference has a list of RF connectors. A BNC connector is very common and is good to 2 GHz. Note that although a connector type can be used to 2 GHz, for example, that does not mean that it is a perfect impedance with no reflections. BNC for example, is not great and has high reflections. Whereas type N is much better, and can also handle more power. As to your question, you need to be more specific. What exactly do you want? UHF Connector at 437 MHz mean what? Most any coax connector will work at that frequency, the question is how well. .
You can try P259 couplers as they are designed for UHF freqs.there is a connector that is used on microwave (radar) frequencies on counters and spectrum analyzers that is about an inch in diameter on the internally threaded outer sleeve with a concentric inner smaller diameter four bladed cylindrical contact sleeve that in turn surrounds the inner conductorI can't remember the nomenclature for it but it is tops for UHF and higher freqsjust now called the local R' Shack toy store and they quit carrying those like just about everything else they had before they became so yuppified. I advise you to google Mouser Electronics and go to their website as they will have every r.f. coupler you could imagine.
