Circuit board RF test with Pigtail assemblies

A good method for probing an RF circuit is to use small diameter semi-rigid cables, commonly referred to as Pigtails, to inject an input signal or sample an output signal. A typical configuration is with an SMA female connector on one end and a straight cut semi-rigid cable on the opposite end. Ater test, the soldered RF Pigtail can be easily removed from the PCB test point. P1dB can also supply the Pigtail cable end trimmed to expose a specific length of the dielectric and center conductor.

P1dB Pigtails

P1dB has Pigtail diameters starting at .020 inches with a center conductor diameter of .004, suitable for probing a miniature 0201 RF pad. Popular Pigtail diameters include .020, .034 and .047. Most P1dB Pigtails are semi-rigid, but conformable coax cable options are also available from P1dB. Popular lengths for standard Pigtails are 2, 4 ,6 and 9 inch, but P1dB has also supplied many custom sizes. Standard sizes in stock at P1dB.

For customer’s that require small diameter semi-rigid assemblies with connectors on both ends, P1dB stocks popular length SMA to SMA assemblies using either .034 or .047 diameter semi-rigid. Custom lengths and connector options are available, usually within 30 days.
