Understanding and choosing GHz-range coaxial connectors and cable assemblies
An example of an SMB connector is the 61611002121501, a male pin, right angle, through-hole, solder connector jack, with a VSWR of 1.5 and an insertion loss under 0.2 dB (Figure 5). Like the SMA device, it is also rated at 500 mating cycles. •SMP series : These miniature connectors with both slide-in and snap-on features can be used in applications up to 40 GHz. They are available with three interface types: full “dent” with maximum retention for high vibrant resistance (100 cycles); limited dent with medium to low retention (500 cycles); and smooth bore (1000 cycles) with the lowest retention achieved via sliding contacts for modular systems and applications (Figure 6). One of the connectors in this series is the 60114202122305, a surface mount, edge card connector with an extended solder leg for circuit boards having up to a 1.2 mm maximum thickness (Figure 7). It is specified to have a VSWR of 1.5 and an insertion loss of 0.42 dB from DC to 12 GHz.
