Rf Cable Connector Loss

Example of rf cable loss calculator.

Rf cable connector loss.

N type connectors are designed to satisfy the need for a durable weatherproof medium size rf connector with consistent performance which includes models that support up to 18 ghz. The system designer also derives inputs from the cable and connector manufacturer s catalogue. Reflected losses are those losses caused by the vswr of the connector. There are 3 main causes of insertion loss.

For example a system designer in his system design calculation has budgeted a 2 db loss including 0 5 db connector loss at both ends of the cable between the amplifier output and the antenna port input of a radio. Standard n coaxial cable and corrugated n helical and annular cable. Insertion loss expressed in db is defined as 10 log po pi where po power out and pi power in. Pasternack carries a huge selection of microwave parts rf parts cables connectors modulators adapters attenuators plus much more.

0 06 sqrt 1 5 0 06 sqrt 1 5 k1 and k2 values. Pasternack rf cables in coax or twinax designs may be available in corrugated flexible formable or semi rigid versions. Headquartered in danbury connecticut usa amphenol rf has global sales marketing and manufacturing locations in north america asia and europe. For example connector loss db for a cable at 1500mhz with two straight sma fittings will be.

Insertion loss 15 db maximum at 10 ghz. Reflected losses dielectric losses and copper losses. Amphenol rf s n type connector features a threaded coupling mechanism and is fully interchangeable with n type connectors made to the mil c 39012 specification. 0 06 for each straight connector 0 15 for each right angle connector.

Connector loss factor x sqrt fghz loss factors for sma connectors are. Rf cable loss 6 93 db 100ft 10 4 db 150 ft rf coaxial cable loss formula. Following rf coaxial cable loss formula is used in this calculator is also mentioned. There are two families of type n connectors.

This multiplier factor is why you should keep cable installation lengths between radios and antennas as short as practical. Rf leakage 90 db minimum at 3 ghz. Line loss of a cable includes connector loss at each end. These characteristics are typical but may not apply to all connectors.

Rf twinax and coax cables are built in low loss and standard performance versions ranging in size from 0 020 to 0 945 inches in diameter. Bulk quantities shipped same day. Loss is a length multiplier so a 200 ft length would have twice the loss shown above and a 50 ft length would have half the loss.
