Maximum VSWR is 1.20 (~21dB) at 11GHz Molex £1.37(1) [Farnell][1] [![enter image description here][2]][2] [![enter image description here][3]][3] [Molex 0733910060 $3][4] (1) 18GHz When you find an RF connector with no VSWR or Return Loss specifications, **be very concerned.** Consider machine and plating tolerances and the precision of the feed pin , how its soldered and any variations. These all significantly affect Return loss at 1GHz and much more at 10GHz etc... Then decide if 10 dB RL is adequate for a cheap connector. You ought to expect this in cheap mass-produced RF connectors without quality controls. Would rather pay extra for 30dB .. You can't afford 40dB or even need it because the geometric tolerances are < 100ppm and dielectric tolerances for d constant, also very tight. Since you asked about 100 mil boards, I assume rigidity is important to you. In this case consider adding rigid substrate or other stiffener mechanics. From my experience, SMD connectors are just bad news mechanically for any type with forces applied to the cable and jack. But I understand if you have a height restriction or packaging problem. There are alternatives. yours on left, on right Amphenol p.n. 901-10511-3 $2.50 left , $13 right [![enter image description here][5]][5] Edge connectors take a lot of abuse and SMA connectors MUST be careful torqued by a calibration tool for optimal performance.
