RF Interconnect for 18 GHz Signal Paths
The 901-1GA200000AE: The threaded fastening and flange mount secure the connector to a panel or bulkhead, while the gold-plated stainless steel body resists corrosion in outdoor or industrial environments.
Sizing the Termination for Field Assembly
Contact termination is solder cup, meaning the coaxial cable center conductor is soldered directly into the cup — no crimp tool required. This makes the connector field-serviceable for prototype runs or repair, though the solder joint must be inspected for voids to avoid impedance bumps above 10 GHz. Shield termination is also solder, so the braid is soldered to the shell body for a low-inductance ground path.
Mating and Cycle Life
The beryllium copper center contact retains its spring force over that life, and the gold-on-gold mating surfaces prevent fretting corrosion. The threaded coupling nut on the mating plug (standard SMA male) provides vibration-resistant retention — no lock-wiring needed for most rack or panel applications.
Comparing Termination Styles: Solder Cup vs. Solder Tab
The sibling 901-2PF100000AE is electrically identical — same 50 Ohm impedance, 18 GHz bandwidth, stainless steel body, and 500-cycle rating — but uses a solder tab instead of a solder cup for center contact termination. The solder tab is a flat lug that the cable center conductor is soldered to, which can simplify strain relief when using a heat-shrink boot. The 901-1GA200000AE's solder cup is more common for direct cable termination without additional hardware. Both are active and panel-mount with flange.
