Overview
An RF terminator (also called a load or dummy load) is a passive device used to absorb RF energy and prevent signal reflections in transmission lines or unused ports. It provides proper impedance matching typically 50 ohm or 75 ohm ensure system stability and minimize standing waves (VSWR). By safely dissipating RF energy as heat, terminators maintain signal integrity and protect equipment from damage caused by mismatched or open-ended lines.
Features
Impedance: Commonly 50 ohm (for RF/microwave systems) or 75 ohm (for broadcast and video systems).
Frequency Range: Available up to 110 GHz depending on the design.
VSWR Performance: Low VSWR ensures minimal reflection across the operating frequency band.
Cooling: High-power terminators may use heatsinks or forced air for thermal management.
Applications
Terminating unused RF ports on splitters, couplers, or test equipment
Simulating system loads during design and testing
Absorbing excess RF power in transmitters or amplifiers
Ensuring stable operation of distributed antenna or broadcast systems
railway communications and signaling systems
MRI, CT, and ultrasound imaging devices
in-vehicle infotainment and connectivity systems

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.
