Overview
High-frequency applications demand precision and reliability, and the BMA connector series excels in meeting these requirements. With a maximum operating frequency of 22.00 GHz, it is well-suited for use in microwave systems where signal integrity and performance are paramount. The coupling mechanism employed by BMA connectors is known as slide-on/push-on coupling. This mechanism allows for a quick and secure connection, making it ideal for applications where ease of use and speed of connection are essential. In terms of interface standards, the BMA connectors adhere to the IEC 61169-33 and MIL-STD-348B standards. These standards ensure that the connectors are designed and manufactured to meet rigorous specifications, guaranteeing compatibility and interoperability with other equipment and components that also comply with these standards.

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.
ROHS & REACH Compliance
Our products fully comply with ROHS & REACH regulations.
Does LENORF Offer Military-Grade Products?
Yes. We are honored to provide military-grade products with exceptionally stable quality.
MOQ (Minimum Order Quantity)
Regular connectors: 500 PCS
Adapters: 100 PCS
Military connectors: 100 PCS
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.
Materials
Common materials include:
Body: Brass, stainless steel
Insulator: PTFE, PEEK
Contacts: Brass, phosphor bronze, beryllium copper
Other: Aluminum, titanium alloy
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 is 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.
