3-2) i-Fit exceeds precision of solder

I-PEX's patented i-Fit solderless terminating technology vs. solder termination outperforms in a side-by-side VSWR comparison. Solder processes introduce variability and inconsistency from harness-to-harness. The i-Fit method removes the variability of solder thereby increasing the repeatability and precision of electrical performance.

3) Unique Option:  MHF-SW23 Plug

The I-PEX MHF-SW23 Plug is a unique plug option for the MHF-SW23 switch connector. It allows for a permanent bypass of an on-board chip or PCB antenna in favor of an external antenna with better performance. The MHF-SW23 plug option also allows for space saving designs. Instead of a standard MHF receptacle (operation) AND MHF-SW23 (test) the MHF-SW23 switch and MHF-SW23 plug provides a path for saving PCB space in space saving designs.
