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.

What is the difference between RF connectors and coaxial connectors?
They are often used interchangeably. However: Coaxial connector refers to the physical design (shielded cylindrical form). RF connector emphasizes its use in radio-frequency applications. Most RF connectors are coaxial.
What is “reverse polarity” (RP-SMA, RP-TNC)?
Reverse polarity means the gender of the center pin is swapped while keeping the outer body style unchanged. It was introduced to comply with regulatory requirements in Wi-Fi devices and to prevent connection with standard SMA/TNC.
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.
