N-Type Plug for RG-402 Semi-Rigid — 6 GHz, Low PIM, Weatherproof
The threaded coupling ensures a vibration-resistant mate, and the weatherproof ingress protection allows outdoor or washdown deployment without a secondary boot.
What the 1500 V and 0.05 dB Ratings Mean for the RF Path
The 1500 V voltage rating is high for an N-type interface — this plug is sized for the peak envelope power in a 50 Ohm system carrying several hundred watts CW, not just a low-power signal line. The 0.05 dB insertion loss is a benchmark for a precision N-type; it keeps the power budget tight in a multi-connector feed string. The silver-plated centre contact (brass body, white bronze finish) handles the current density at that power level and resists oxidation over the 500 mating cycles. The Low PIM construction means the mechanical interfaces are designed to minimise passive intermodulation products — critical when this connector sits in a transmit path where IM products fall into the receive band.
Cable and Termination — RG-402 Only, Solder Attachment
This plug is listed for RG-402 (.141" semi-rigid) cable only. That means the assembly requires a controlled soldering process: the PTFE dielectric can reflow if overheated, so a heat-sink or short-duration iron tip is recommended. The free-hanging, in-line mounting style is intended for cable assembly, not panel mounting. For a panel-feedthrough N-type, look at the Amphenol RF 172133 series jacks or bulkhead receptacles.
