SMA Jack for Board-Edge RF Launches
The 901-10510-2: It is the single-port member of the 901-10 base series, carrying a 50 Ohm impedance and rated to 26.5 GHz — a full DC-to-microwave bandwidth that covers Wi-Fi, 5G sub-6 GHz, satellite L-band, and test-equipment IF stages. The threaded fastening (MIL-STD-348 interface) gives a vibration-resistant mate that holds its torque under thermal cycling, and the 500 mating cycles mean this jack survives repeated field reconnections without degrading the centre-contact wipe.
What the 50 Ohm and 26.5 GHz Ratings Mean for the RF Path
The 26.5 GHz maximum frequency means the connector maintains a controlled impedance launch well into the K-band; above that, the interface geometry starts to radiate. For a board-edge launch, the right-angle through-hole pins keep the signal path short to the PCB trace, minimising the stub inductance that would otherwise degrade return loss above 10 GHz. The 170 V voltage rating is the breakdown limit across the dielectric — in practice, the RF power handling is limited by the centre-contact current density and the cable's own rating, not the connector's voltage spec.
Mounting and Termination — Board Edge, End Launch, Right Angle
This jack mounts at the board edge with a right-angle through-hole footprint — the body sits flush against the PCB edge, and the four through-hole posts (two signal, two ground) solder into plated holes. The contact termination is solder as well — no crimp, no clamp — so the centre pin is soldered directly to the PCB trace.
