Collection: RF Adapter

Shop YILIANDUO RF coaxial adapters for SMA, RP-SMA, BNC, UHF, N, QMA, F-type and related connector systems. Options include straight, right-angle, in-series, cross-series and multi-piece adapter kits.

How to choose an RF coaxial adapter

• Connector family: Identify both connector standards before ordering. SMA, RP-SMA, QMA, BNC, UHF, N and F-type interfaces are not interchangeable.
• Gender and center contact: Check the plug or jack body and the center pin or center hole separately. RP-SMA can reverse the center contact arrangement used by standard SMA.
• Adapter format: Choose an in-series or cross-series adapter, then confirm straight or right-angle orientation and whether the listing is a single configuration or a multi-piece kit.
• Electrical rating: Match system impedance and the required frequency range using the selected product page. Do not infer electrical limits from housing shape alone.

Choosing SMA to QMA adapters

The current range includes SMA-to-QMA, RP-SMA-to-QMA and multi-type QMA adapter options. QMA uses a quick-lock coupling, while SMA and RP-SMA use threaded coupling. Confirm the exact connector at each end, center contact, orientation, package quantity and product-level rating before connecting equipment.

Use the specifications and package list on each product page as the final reference. Equipment names alone may not identify the installed RF connector.
