Introduction

The Taoglas CAB.058 is a 0.047” semi-rigid coax pigtail with SMA connector that is ideal for RF

circuit debug and design verification. The pigtail is 50mm long and comes stripped and tinned

to expose a short length of the inner conductor, thus removing the need to make your own.

The CAB.058 acts as a 50 ohm transmission line to connect your test equipment to your

printed circuit board and has a SMA female connector making it the proper mate for most coax

cables used in design labs, eliminating the need for additional adapters. Semi-rigid coax also

has the best attenuation of all micro-coax types.

In order to make a proper connection to the PCB without causing an impedance mismatch, the

cable jacket needs to be soldered to the PCB ground and the inner conductor gets soldered to

the RF transmission line. The CAB.058 has a smooth, semi-rigid, metallic jacket that makes it

very easy to solder the jacket to the PCB ground.

The thinner 0.047” cable diameter makes it easier to solder onto densely populated circuit

boards. The semi-rigid nature of the cable also allows you to easily bend the pigtail to your

convenience, yet holds its position to prevent toppling over and shorting nearby components.

Taoglas provides customized length and connector variants subject to MOQ. Contact your

regional Taoglas office for details.
