What this adapter does in the RF path
The TE Connectivity 1513743-1 is a between-series RF adapter that transitions from a QSL jack, female socket to an SMA jack, female socket. It is a board-mount adapter, not an in-line barrel — it lands on the PCB and presents an SMA interface for cabling or test equipment while the QSL side connects to the board trace. The 50 Ohm impedance keeps the signal path matched through the transition, and the 6 GHz max frequency covers the bulk of commercial RF work including Wi-Fi, ISM bands, and lower microwave test setups. With 500 mating cycles on the contacts, this adapter is built for test bench reconfiguration or field-swappable modules where the SMA side sees repeated connect-disconnect duty.
SMA vs QSL — what the interface swap means
SMA is the ubiquitous threaded RF interface for DC to 18 GHz work, while QSL (Quick Signal Lock) is a push-on, snap-lock variant designed for faster mating in board-level interconnects where a wrench is impractical. The 1513743-1 lets you keep the QSL on the PCB side — saving board space and assembly time — while the SMA end mates to standard SMA cables, attenuators, or test gear. The female-to-female gender on both ends means it accepts male-terminated cables or modules on either side. No impedance bump or mode conversion is introduced at the junction because both interfaces are 50 Ohm by design.
