The first sample worked. The production batch did not. This is a situation RF engineers see more often than expected. A prototype cable assembly may pass a basic signal check because the cable is short, installed in open space, and tested under...

A cable assembly can pass continuity testing and still become the weak point of an RF system. This happens more often than many buyers expect. The connector mates correctly, the cable length matches the drawing, and the first prototype works on the bench. Problems appear...

A cable assembly can pass continuity and still be the wrong RF part. That situation appears more often than many buyers expect. The connector mates correctly, the cable length matches the drawing, and the first sample works during bench testing. Problems usually appear later: the...

A test setup can fail even when every connector appears to fit correctly. A common RF sourcing mistake happens when an engineer replaces a missing interface with a physically compatible adapter but ignores impedance, frequency range, or connector gender. The assembly connects mechanically, the signal...

A cable assembly can pass a continuity test and still be the wrong RF part. This happens more often than many buyers expect. The connector mates correctly, the cable looks acceptable, and the first sample works on the bench. Problems usually appear later: the cable...

A connector can fit perfectly and still create an RF problem. This situation appears frequently during prototype testing. A cable is selected because both ends match the equipment ports, the mechanical connection looks correct, and the first test result seems acceptable. After moving into a...

A cable assembly can pass continuity and still be the wrong RF part. This happens more often than many buyers expect. The SMA connector mates with the device, the N Type connector fits the antenna cable, and the first bench test appears normal. The problem...

A coax adapter can look like a simple mechanical part. Two connectors fit together, the threads engage, and the signal appears to pass. In a real RF system, that first impression can be misleading. A common sourcing mistake happens when engineers select an adapter only...

A connector can pass continuity and still be the wrong RF connector for the job. That is a common problem in RF sourcing. The part fits the port, the thread starts smoothly, and the cable looks acceptable in photos. Later, the same assembly shows unstable...

A wireless device can fail before the antenna itself becomes the problem. A common example happens during hardware integration: the antenna fits mechanically, the connector threads correctly, and the first prototype passes a bench test. After moving into production, engineers discover unstable signal levels, unexpected...

A BNC connector can still look correct even when the RF connection is wrong. This happens often during equipment integration. A technician finds an older signal generator with a BNC output and a newer RF module using SMA. The quick solution seems obvious: add a...

A cable can pass continuity and still fail the RF job. That is where many connector mistakes start. The center conductor touches. The shield is connected. The nut tightens. On a simple meter, nothing looks wrong. But once the assembly is used in an antenna...
