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
robotics and industrial automation requiring RF links
smart meters and remote monitoring devices

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’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.
What’s the difference between threaded, bayonet, and push-on RF connectors?
Threaded (SMA, N, TNC): Secure, vibration-resistant. Bayonet (BNC): Quick connect/disconnect. Push-on (MCX, SMP): Ultra-fast, compact, used in high-density modules.
Are RF connectors interchangeable between brands?
Yes, if they follow the same standard (e.g., SMA-to-SMA). However, tolerances, plating, and dielectric quality vary — mixing low-quality and precision connectors can damage equipment.
