TNC Jack That Holds the Line to 11 GHz
What the 11 GHz and 0.18 dB Ratings Tell the RF Designer
The 11 GHz frequency ceiling is the defining spec on this jack — it is not a general-purpose signal connector. The 0.18 dB insertion loss at that frequency is a tight figure, meaning the impedance transition through the solder joint and the PTFE dielectric is controlled. The dielectric stack uses both PBT and PTFE; PTFE handles the RF path, PBT provides the structural support for the centre contact.
Mounting That Fixes the Jack to Both Panel and Board
The mounting combination is panel mount, through hole, right angle — the bulkhead front-side nut secures the jack to the panel face, while the right-angle solder tails route the signal perpendicular to the board edge. This footprint is common for RF jacks on the edge of a PCB that sits inside a shielded enclosure.
500 Mating Cycles and 500 V — What They Mean for Field Service
The 500 mating cycles is the standard for a threaded RF connector that gets disconnected a few times a year in the field — not a test-bench connector that sees daily swaps. The 500 V rating is high for a 50 Ohm RF jack; the creepage path is carried by the threaded interface, not the signal pin.
