Compatability

There are several connector styles that *look* quite similar. There is the GSC connector from Murata, the Sunridge MCF connector, the Hirose U.FL connector and UMCC connector (from Tyco / TE Connectivity). Apparently things arent complicated enough so the UMCC as well as the U.FL connector have different sub types:
UMCC has "Style A" and "Style B".
U.FL has female connector types
U.FL-LP-040
U.FL-LP(V)-040
U.FL-LP-062
U.FL-LP-066
U.FL-LP-088
which apparently all mate to its male counter part U.FL-R-SMT-1 [1]

UMCC Style A mates with UMCC Type II and III as well as Hirose U.FL(v)
UMCC Style B mates wit UMCC Type I as well as GSC [2]

If someone could verify this (maybe all those connectors mate?), this information could be included in the article. --Moritz der Moralapostel (talk) 15:51, 29 October 2012 (UTC)[reply]

There's a good diagram on page 2 of the Hirose training module (interactive or PDF; both already are linked in the article) that may help. The table on page 6 explains some of those specific 'sub-types'.

The Hirose SMT connectors shown in that figure, in terms of decreasing nominal mating height, are:

H.FL / Hirose H.FL: 3.00 mm mating height; 5.0 mm x 4.5 mm board mounting area
E.FL / Hirose E.FL: 3.00 mm mating height; 3.4 mm x 3.4 mm board mounting area
U.FL / Hirose U.FL: 2.40 mm mating height; 3.0 mm x 3.1 mm board mounting area
U.FL-LP(V): 1.90 mm mating height; 3.0 mm x 3.1 mm board mounting area
W.FL-LP(G): 1.65 mm mating height; 2.0 mm x 2.0 mm board mounting area
W.FL / Hirose W.FL: 1.40 mm mating height; 2.0 mm x 2.0 mm board mounting area

Additionally, that pages 8 & 9 of that reference confirms that U.FL are rated for 30 connection cycles while the smaller W.FL connectors are only rated for 20 cycles.

Diameter is 2.0mm

There are various references to 1.9mm or 2.4mm, but those are the mated height, not the connector diameter. — Preceding unsigned comment added by 49.176.98.26 (talk) 20:55, 30 April 2013 (UTC)[reply]

I believe part of the confusion is that some sources list dimensions for the amount of circuit board space taken up by a connector, and others may refer to the diameter of the connector mating surfaces themselves.

U. FL stands for ...

On this page we should be able to find what U. FL stands for. — Preceding unsigned comment added by 2601:14D:8000:6956:966:C625:97CC:5948 (talk) 01:57, 2 March 2018 (UTC)[reply]

Merge W.FL

As the W.FL is probably a WP:PERMASTUB, I think it would make sense to merge it into this article. Initramfs (talk) 20:23, 22 November 2019 (UTC)[reply]

Merger complete. Klbrain (talk) 11:27, 16 July 2020 (UTC)[reply]

Add other similar connectors here (or somewhere else)?

As the current article describes a connector compatible with the MHF1/MHF I ('Mobile High Frequency'??) connector, would it make sense to reference the newer variations as well, such as:

MHF3/MHF III
MHF4/MHF IV (apparently used by some M.2 WiFi5 cards such as the 'Intel Dual Band Wireless-AC 8265')^[a]

This information could also go on the List of RF connector types page, but at least two of the relevant 'Micro' connectors redirect to this article anyway.

^ Intel punts to the PCIe M.2 specs (current version paywalled; a copy of v1.0 is available) instead of directly describing which connectors it uses, only to mention that they are "2mm" connectors.
