Coaxial Terminations

CL-series coaxial terminations with model-specific frequency, average and peak power, VSWR, connector and impedance data. Send your RF conditions for model matching.

CL-Series Coaxial Terminations

Match the termination to the real RF load — not a family-wide headline.

Dolph Microwave supplies free-standing convection-cooled coaxial terminations for transmitter and antenna terminals, test loads, and matched ports in RF and microwave assemblies. Frequency, VSWR, peak power and connector limits are model-specific, so we match the part number to your operating conditions before quotation.

Choose the Correct RF Component

If the job is not load termination, move to the right component family.

This avoids forcing a termination into an application that needs attenuation or interface conversion.

Need signal reduction?
Use a coaxial attenuator when the signal must continue through the RF path at a reduced level.
Coaxial Attenuators
Need connector conversion?
Use a coaxial adapter when the RF path remains coaxial but the connector interface changes.
Coaxial Adapters
Need a cable-end interface?
Review connector options when the requirement is cable connection rather than load absorption.
Coaxial Cable Connectors
Need coax-to-waveguide transition?
Use a waveguide-to-coaxial adapter when the transmission medium changes between coax and waveguide.

How We Handle the RF Requirement

A short engineering check before quotation.

1. Match the operating point
Frequency, average/peak power, impedance and connector are checked together.
2. Check the model row
We use the model-specific VSWR and interface limits instead of a generic family claim.
3. Return the next step
The relevant configuration and technical documentation are aligned before order confirmation.
COMPANY
Founded in 2001
TECHNICAL BASIS
Published model datasheet
Specifications can be checked before order release.
ORIGIN
Designed and made in China
As stated in Dolph technical documentation.
WARRANTY
One-year published warranty
For defects in materials and workmanship under the stated terms.
Ready for Model Matching

Send the operating conditions. We will work from the actual model limits.

Frequency band, average/peak power, connector and gender, impedance, quantity and any installation constraint are enough to start.
