Overview
An RF adaptor (Radio Frequency adapter) is a component used to connect two RF connectors or interfaces - either of different types or the same type. It enables the transmission of high-frequency signals with minimal loss or interference, and is typically used in the following applications: network analyzers, spectrum analyzers, and oscilloscopes,RF/microwave test benches and calibration equipment,missile guidance, drones, and satellite payload systems .
Application
Connecting antennas to RF equipment
Linking test equipment (like spectrum analyzers or signal generators) to DUTs (devices under test)
Integrating components in RF communication systems (e.g., Wi-Fi, LTE, GPS, IoT modules)
network analyzers, spectrum analyzers, and oscilloscopes
RF/microwave test benches and calibration equipment
missile guidance, drones, and satellite payload systems

FAQ
Sample Delivery Time
Regular models require 15 days, while some complex connectors require 25 days.
Sample Fee
Most RF connectors are CNC-machined parts and do not require mold-making.
However, each part needs to be fine-tuned on the CNC machine. Typically, a single sample costs $200.
This fee will be refunded after a 5K bulk order.
Guarantee
Brass RF connectors come with a one-year warranty.
Stainless steel connectors come with a three-year warranty.
The lifespan also depends on the contact material beryllium contacts offer better durability.

What’s the lifespan of an RF connector?
Connector durability is rated in mating cycles: General-purpose connectors (BNC, SMA): 500 cycles. Precision connectors (2.92 mm, 2.4 mm): 500 cycles or less. Rugged telecom connectors (N, 7/16 DIN): 500 cycles.
Can RF connectors be reused?
Yes, but performance degrades with wear. Precision connectors (used in test equipment) should be handled carefully—damage to threads or pins increases VSWR and insertion loss.
What’s the difference between threaded, bayonet, and push-on RF connectors?
Threaded (SMA, N, TNC): Secure, vibration-resistant. Bayonet (BNC): Quick connect/disconnect. Push-on (MCX, SMP): Ultra-fast, compact, used in high-density modules.
Are RF connectors interchangeable between brands?
Yes, if they follow the same standard (e.g., SMA-to-SMA). However, tolerances, plating, and dielectric quality vary — mixing low-quality and precision connectors can damage equipment.
