The 901-144-PF8: It's a through-hole mount with press-fit shield termination — the shield gets pressed into the board, no solder on the ground plane, which keeps the RF launch clean. Rated to 18 GHz, it covers the common RF bands up through Ku-band satellite and microwave links.
Mounting and Termination Check
Through-hole mounting with press-fit shield termination — the shield barrels press into plated through-holes, no solder wicking up the dielectric. The center contact is press-fit as well, so the whole connector seats in one operation. Mates with any standard SMA male plug with threaded coupling; the threaded fastening type gives a vibration-resistant joint. No special tooling beyond a press or arbor press for the shield.
What the 50 Ohm and 18 GHz Ratings Mean for Your Signal Path
The 18 GHz max frequency means this jack passes signals cleanly up through the Ku band; above that, the geometry starts to radiate. For a board-edge launch, the press-fit shield keeps the ground return path short, which preserves the impedance through the transition from coax to PCB trace.
