If 1.85 mm and 2.4mm connectors mate together then why would someone buy a 1.85mm to 2.4mm adaptor?
I figured that 1.85 mm and 2.4 mm connectors mate or are mechanically compatible. So, wondering why would someone buy a 1.85mm to 2.4mm adaptor (50 GHz bw) like the one mentioned in the data-sheet link below?
I understand that if the test equipment is designed for 67 GHz operation (for 1.85 mm connector) then using such adaptor will limit the operation down to only 50 GHz. so not sure why would someone want to use such adaptor and limit the operation only up to 50 GHz (may be noise or insertion loss reason?) – would be wonderful to see some intuitive discussion on this.
Is there any other specific reason for using such adaptor? For example, will my connector be damaged if I connect 1.85mm (M) into 2.4 mm (F) even though they are said to be mechanically compatible?
One reason would be reliability. The smaller the connector, the more likely it is damaged, so if you don’t need to go to 67 GHz, keep it at 50 GHz. Less expensive cal kit too.
I have a 67 GHz PNA at work where I ordered 1.85 mm NMD to 3.5 mm cables, and a 50 GHz PNA with 2.4 mm NMD to 3.5 mm. Of course I have full 1.85 mm and 2.4 mm cables, but only hook those up when I need the extended frequency. Otherwise keep everything at 3.5 mm.
Years ago some idiot at work force fit a 3.5 mm onto a 2.4 mm brand new spectrum analyzer. The threads are not even compatible (for that reason), but a monkey with a wrench can pull it off.
