Coaxial Receptacle for Board-Edge RF — Hirose GT13S-1PP-DS
The Hirose GT13S-1PP-DS is a single-port coaxial receptacle from the GT13 series, designed as a 50 Ohm impedance interconnect for RF signal paths up to 1 GHz. It is a right-angle through-hole mount with a male pin centre contact, terminated by solder to the PCB. The housing is gray polybutylene terephthalate (PBT), and the centre contact is tin-plated brass. This connector is built for one-time or infrequent mating — the 30-cycle rating tells you it is a set-and-forget port, not a daily-use test point.
What the 50 Ohm and 1 GHz Ratings Mean for Your RF Path
The 1 GHz maximum frequency is the practical bandwidth ceiling; above that, the PBT dielectric and tin-plated centre contact start to introduce losses and impedance discontinuities. For sub-1 GHz applications — GPS, ISM-band radios, cellular, WiFi at 2.4 GHz is out of range — this connector is a clean, cost-effective board-edge launch. The 250 V rating covers the DC bias voltage that often rides on the RF line in active antenna or LNA circuits.
Mounting and Mechanical Retention — Board Lock and Flange
The mounting flange adds a second mechanical retention point, typically bolted to the chassis or enclosure panel. Together, the board lock and flange mean the solder joints are not the sole mechanical support; the connector can handle the weight and strain of a semi-rigid coaxial cable without fracturing the solder fillets over time.
