Overview
TRB connectors are available in configurations with 2-, 3-, or 4-lug bayonet coupling, as well as push-on versions. Designed for twinaxial and triaxial cable systems, they are mechanically similar to BNC connectors and share the same outer dimensions. TRB connectors are commonly used in applications where high noise immunity is required and signal frequencies typically remain below approximately 500 MHz. TRT connectors are closely related to TRB connectors, with the primary distinction being the coupling mechanism. While TRB uses a bayonet interface, TRT connectors employ a threaded coupling for enhanced mechanical security. In this respect, TRT can be considered the twinaxial/triaxial counterpart to the TNC connector in the BNC family. Like TRB, TRT connectors maintain the same form factor as BNC/TNC connectors and are well suited for 鈥渘oise-free, guarded鈥?circuit applications requiring stable, low-noise signal transmission.

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
