Overview
An RF attenuator is a passive device that reduces the power level of an RF signal without distorting its waveform. By introducing a known loss, attenuators help manage signal levels, protect sensitive components, and improve system performance. They are available in fixed, variable, and step types, and are commonly specified by attenuation value (dB), frequency range, power handling, and connector interface.
Features
Attenuation Control: Provides precise reduction of signal power in defined steps (e.g., 1 dB, 3 dB, 10 dB) or continuously adjustable
Frequency Range: Can support DC to 50+ GHz depending on the design.
Low Insertion Loss: Ensures minimal impact on signal transmission and VSWR performance.
Power Handling: Low-, medium-, and high-power models available, from a few watts to hundreds of watts.
Impedance Matching: Typically 50 ohm (some are 75 ohm), ensuring minimal reflection and low VSWR.
Types: Fixed attenuators, variable attenuators, programmable or step attenuators.

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 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.
How do environmental conditions affect RF connectors?
Temperature extremes can cause expansion/shrinkage and change performance. Humidity and salt spray may cause corrosion (use stainless steel or weatherproof designs). Vibration may loosen bayonet types — use threaded connectors in harsh environments.
Can RF connectors be adapted from one type to another?
Yes, RF adapters (e.g., SMA-to-N, BNC-to-TNC) exist. But:Each adapter adds insertion loss and possible VSWR increase.Avoid stacking multiple adapters in sensitive applications.
