Rf Cable Connector Loss

Insertion loss expressed in db is defined as 10 log po pi where po power out and pi power in.

Rf cable connector 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. Rf leakage 90 db minimum at 3 ghz. This multiplier factor is why you should keep cable installation lengths between radios and antennas as short as practical. Rf cable loss 6 93 db 100ft 10 4 db 150 ft rf coaxial cable loss formula.

There are 3 main causes of insertion loss. Connector loss factor x sqrt fghz loss factors for sma connectors are. 0 06 for each straight connector 0 15 for each right angle connector. 0 06 sqrt 1 5 0 06 sqrt 1 5 k1 and k2 values.

Bulk quantities shipped same day. Reflected losses are those losses caused by the vswr of the connector. Headquartered in danbury connecticut usa amphenol rf has global sales marketing and manufacturing locations in north america asia and europe. Pasternack rf cables in coax or twinax designs may be available in corrugated flexible formable or semi rigid versions.

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. Reflected losses dielectric losses and copper losses. 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. Line loss of a cable includes connector loss at each end.

Example of rf cable loss calculator. 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. Pasternack carries a huge selection of microwave parts rf parts cables connectors modulators adapters attenuators plus much more. Following rf coaxial cable loss formula is used in this calculator is also mentioned.

Standard n coaxial cable and corrugated n helical and annular cable. 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. The system designer also derives inputs from the cable and connector manufacturer s catalogue. For example connector loss db for a cable at 1500mhz with two straight sma fittings will be.

These characteristics are typical but may not apply to all connectors. Amphenol rf is the world s largest manufacturer of coaxial connectors for use in radio frequency microwave and data transmission system applications. Frequency 2500 mhz k1 0 11694 k2 0 00036 clf 0 12 l 150ft outputs.
