Overview
The 7/16 DIN connector is a threaded RF connector widely used in high-power,Low VSWR ensures minimal signal reflection and low-PIM (Passive Intermodulation) applications. Its name comes from the dimensions of the inner and outer contacts: 7 mm (outer conductor) and 16 mm (inner conductor). Designed originally in Europe, it has become an industry standard for RF/microwave test benches and calibration equipment,TV and radio transmission systems,Network analyzers, spectrum analyzers, and oscilloscopes and other demanding RF installations.
Features
| High Power Handling | Supports up to several kilowatts of power, thanks to its robust design and low contact resistance. |
| Low PIM Performance | Typically -150 dBc or better, making it ideal for cellular base stations and DAS (Distributed Antenna Systems). |
| Rugged Mechanical Design | Large, threaded coupling ensures secure, vibration-resistant connections. |
| Weatherproof Options | Often available with gaskets or weather seals for outdoor use. |
| Durability | Can withstand repeated mating cycles (>500) |

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 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
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.
