I'm trying to identify the following miniature female RF coaxial connector found on an antenna input of a cheap DVB-T receiver (Sencor brand). I would like to identify the type so that I can get a matching male connector. The inner diameter of the receptacle measures 3.3 mm and the depth is approximately 4 mm. The inner surface is smooth. There are no threads or indents visible. Since it is on a DVB-T receiver, I'm guessing the connector probably has 75 ohm impedance.
Other dimensions I could measure with calipers (approx. where I can only do an estimate):
The closest match I could find is the front end of a SMC plug (without the threads), however the barrel is just slightly too large to fit (3.7 mm diameter). MCX also appears too large (3.8 mm).
It looks like an MCX. The inner diameter of the receptacle is spec'd at 3.45 +/- 0.03 mm, which is pretty close to your drawn width of 3.3 mm, and has some measurement error. The receptacle depth is spec'd at 4.0 mm, which matches your drawing. See dimensions labeled B and G in this MCX spec sheet:
