Frequently Asked Questions (FAQ) for Terminations

Below are Frequently Asked Questions about RF ONE’s terminations. If you need more information or have any other questions, please feel free to e-mail us at or call us at 86-755-86705630. We will be very happy to assist you.

Does RF ONE offer low PIM terminations?
Our catalog terminations (RFT series) can only meet the min PIM -110dBC, typical -115dbc (measured at 1800MHZ, 2*20W or 2*10W depending on the termination’s rated power).
If you need better PIM level such as 150dBc,160dBc or 170dBc, please visit our website page Low PIM Passive Components, where we specially list the low PIM terminations.

Can RF ONE provide conduction cooled terminations?
If not specified otherwise, the terminations on our catalog from 2W to 500W are convection-cooled.
We also offer conduction & convection combined cooled RF loads with custom package size. For example, we have built DC-8GHz 150W and 250W terminations with flat bottom (refer to below photo).
When customer needs purely conduction cooled terminations, check with our sales for your specific requirements.

What substrates does RF ONE use for the resistor terminations?
RF ONE utilizes Aluminum Nitride or 99% Aluminium Oxide material in the resistive circuit. These materials improve the cooling capabilities of the coaxial termination  and provides better aging performance.

What is the warranty of RF ONE’s terminations?
All high power terminations (100W and higher) are warranted 12 months since ship date. Check our Terms and Conditions for detailed warranty policy.

What are the distinguishing advantages of RF ONE’s terminations?
1. We use a Beryllium Copper spring contact to compensate the mechanical shrinkage over temperature changes.
2. RF ONE only utilizes high quality stainless steel or brass materials for the connectors which are machined to tight tolerances. The center contact pin is gold plated BeCu according to MIL-G-5024 to ensure reliable multiple matings.
3. Typical delivery for our catalog terminations is one week delivery.
4. RF One offers the widest selection of coaxial terminations from DC-3GHZ up to 67GHz, available in SMA, N type, BNC, 4.3-10, QMA, QN, 2.92mm, 2.4mm, 1.85mm, male or female genders.
