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: 5G, LTE, Wi-Fi, and satellite communication systems,towers, repeaters, routers, and access points for reliable RF signal transfer,base stations, antennas, and feeder cables .
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)
5G, LTE, Wi-Fi, and satellite communication systems
towers, repeaters, routers, and access points for reliable RF signal transfer
base stations, antennas, and feeder cables

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.

Are RF connectors weatherproof?
Some RF connectors are designed with gaskets and sealing (e.g., N-type, 4.3-10) for outdoor telecom, antennas, and harsh environments. Indoor lab connectors (e.g., SMA, BNC) are usually not weatherproof unless specified.
What’s the difference between male and female RF connectors?
Male: Has a center pin and usually an outer thread or bayonet. Female: Has a receptacle (socket) for the center pin and matching thread. Some connectors (like SMA) can be confusing because “reverse polarity” (RP-SMA) swaps pin/socket configuration.
What is VSWR, and why does it matter?
VSWR (Voltage Standing Wave Ratio) indicates signal reflection. Ideal: 1.0 (perfect match). Lower VSWR means less signal loss and distortion.
What are typical applications of RF connectors?
Telecom (5G, LTE, satellite) Aerospace & defense (radar, avionics, secure comms) Test & measurement (network/spectrum analyzers) Broadcast & video distribution Automotive radar and IoT devices Medical imaging & equipment
