Secure Locking SMPS RF Connectors

SV Microwave’s secure locking QuarterBack® SMPS product line expands our trusted QB series with four new high-frequency solutions, including a cable assembly and cable connector for Ø.047" cable type as well as edge launch and surface mount PCB connectors. Newly designed into an even smaller form factor, these connectors feature our high frequency SMPS interface and deliver reliable performance up to 65 GHz. Additionally, this product line features a quarter-turn bayonet-style coupling nut with a locking feature, ensuring robust connectivity in high-vibration environments. Ideal for space-constrained, high-frequency applications, this latest expansion enhances the versatility of the QB family.
