Padma The Molex connector was one that I had George Hubbard design for me back in 2004, when he worked at Molex. It takes a precision flange mount design and incorporates a built in beryllium copper pin that forms a signal contact with pad on a PCB. It was designed specifically to be a low return loss connector for precision measurements. The Samtec flange mount connector is designed to be a low cost connector, similar to other standard SMA flange mount connectors in the industry. The Samtec boys in Harrisburg can give you any information about it that you desire. Depending on your application, it may meet your needs. regards, Scott padma gundala wrote: > Hi, > > Anyone know the technical reason why one costs $40 and the other $3.75 > > Molex SMA Jack/connector :P/N 73251-1850 $40 > and > Samtec SMA Jack :P/N SMA-J-P-H-ST-PN4 $4 > Both are 50ohms, Samtec rates 12.5 GHZ. > > Any inputs from people who have experience using any of the above > is appreciated. > > Thanks a lot. > > Padma > > > ------------------------------------------------------------------ > To unsubscribe from si-list: > si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field > > or to administer your membership from a web page, go to: > //www.freelists.org/webpage/si-list > > For help: > si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field > > > List technical documents are available at: > http://www.si-list.net > > List archives are viewable at: > //www.freelists.org/archives/si-list > or at our remote archives: > http://groups.yahoo.com/group/si-list/messages > Old (prior to June 6, 2001) list archives are viewable at: > http://www.qsl.net/wb6tpu > > > -- Scott McMorrow Teraspeed Consulting Group LLC 121 North River Drive Narragansett, RI 02882 (401) 284-1827 Business (401) 284-1840 Fax http://www.teraspeed.com Teraspeed® is the registered service mark of Teraspeed Consulting Group LLC ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List technical documents are available at: http://www.si-list.net List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
