SMA to SMP-KK-JJ RF Coaxial Connector Straight RG58 Cable

This is a full series straight SMA-SMP coaxial RF adapter, covering three mainstream interface combinations: SMA-JJ (Male to Male)、SMA-KK (Female to Female)、SMA-JK (Male to Female) as shown in the picture. The whole body is forged from solid brass with full thick hard gold plating, which effectively avoids oxidation and high-frequency signal attenuation during long-term laboratory testing and wireless module operation.

One end adopts standard SMA threaded interface compatible with RG58 antenna jumpers, signal analyzers and communication equipment; the other end is miniature SMP push-on blind-mate interface, perfectly matched with SMP PCB board micro terminals of wireless RF modules, solving the problem of incompatible port sizes between test instruments and miniature circuit boards.

Support ultra-wide frequency band DC~18GHz, stable low VSWR performance, suitable for millimeter wave testing, WiFi 6E debugging, 5G sub-6GHz module verification, GPS signal testing and portable wireless measurement equipment. Dual hexagonal wrench limit structure is reserved on both ends, convenient for precise locking without sliding during assembly. All raw materials meet RoHS low-halogen environmental standards, ideal for mass production of wireless communication modules and laboratory precision testing.

Specifications

Advantages

• 3 Complete Interface Combinations Cover All Wireless Module Transition Demands (Core Advantage)

  JJ male-male, KK female-female, JK male-female three full specifications, one series meets all docking scenarios between SMA test equipment and SMP miniature PCB modules, no need to develop multiple single adapters, simplify inventory management.

• DC~18GHz Ultra-Wide Broadband Adapt High-Frequency Millimeter Wave Testing

  Ordinary transition adapters only support up to 6GHz/12GHz; this SMA-SMP series reaches 18GHz, fully compatible with WiFi6E, Bluetooth 5.3, 5G sub-6G, 77GHz radar low-frequency segment laboratory debugging.

• Full Thick Gold Plating Long-Term Stable Test Measurement Performance

  Thick hard gold coating avoids oxidation discoloration of nickel-plated adapters after long-term exposure in laboratories, effectively prevents test data drift caused by increased contact resistance.

• Dual Hex Wrench Anti-Slip Lock Design Easy Precise Installation

  Hex limit steps are reserved at both ends, torque can be accurately controlled by standard wrench, avoid thread damage and impedance deviation caused by manual over-tightening bare threads.

• SMP Blind Push-On Quick Connection Improve Mass Production Efficiency

  SMP end adopts blind-mate push-on structure, no need to align threads, vertical press to lock, greatly shorten the single module test docking time of OEM wireless module factories.

• One-Stop Custom RF Transition Jumper Service

  Can be matched with RG58/RF1.13 coaxial wire to process finished SMA-SMP custom-length signal extension cables, support small batch prototype sampling and mass OEM production for communication test equipment manufacturers.
