mini-phone connector

Also called a 3.5mm or 1/8" connector, it is a plug and socket widely used for analog audio signals in portable devices. For example, the headphone jack on iPods, tablets and portable DVD players is a mini-phone socket.

2.5mm Sub-Mini Phone
The smaller "sub-mini connector" with a thinner shank (2.5mm - 3/32") has been used on cellphones and other compact devices. See phone connector, RCA connector, A/V ports, Lightning to 3.5mm adapter and plugs and sockets.


You Can Tell By the Plug
Plugs with two divisions (TS) are monaural, while three divisions (TRS) are stereo. Headset plugs have a fourth line (TRRS) for the microphone. Smartphones accept both three-wire cables for headphones and four-wire cables for headsets. See tip and ring.

Moreover, most budget smartphones also use the 3.5 mm connector as an antenna for FM radio (unless the antenna is housed in the smartphone itself).
This ensures that the pin and socket will not see excessive wear and mating stress seen by misalignment in an SMA or 3.5 mm connector. The 2.92 mm connector also has a thicker wall than a standard SMA.
The adapters are available in all sex configurations--male-to-male, female-to-female and male-to-female for 2.4, 2.9 and 3.5 mm connector configurations.
Since the measurement frequency will not be higher than 18 GHz, a 2.4 mm connector is not required; a 3.5 mm connector is acceptable.
This situation can be changed if an air-line interface (similar to a 3.5 mm connector interface) is used instead of the fully dielectric-loaded SMA line.
Zero gap inner and outer conductor seams of 3.5 mm connectors have a return loss of approximately 51 dB, and 2.94 mm connectors' return loss is approximately 49 dB.
Although the 3.5 mm connectors mechanically interface with SMA and 2.92 mm without the need of an adapter, there is a discontinuity at the interface that needs to be resolved.
The GPC-2.92-TRL-CV calibration kit employs K connectors and can be used to calibrate a network analyzer with K connectors from 0.5 to 40 GHz, a network analyzer with 3.5 mm connectors from 0.5 to 26.5 GHz and any of the analyzers with SMA connectors from 0.3 to 18 GHz, as long as they have the TRL software option.
One of the services measures noise standards at discrete frequencies of 12.4, 13.5, 14, 15, 16, 16.5, 17 and 18 GHz using type N and 3.5 mm connectors in coaxial cable.
