Coaxial Terminations
CL-series coaxial terminations absorb RF power at unused ports and test outputs. Dolph lists 50 Ohm models and selected low-power 75 Ohm versions. Choose frequency, average power, peak power, connector and cooling conditions from one model row; the family maxima do not describe a single load.

Confirm the selected part number against a current drawing where the published table uses a legacy connector label. Peak-power figures also require pulse width, repetition rate and duty cycle; an average-power rating alone does not establish pulse capability.

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.
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.
Send frequency band, system impedance, connector series and gender, average power, peak power and pulse conditions. Include ambient temperature, airflow or enclosure constraints and quantity so the proposed load can be checked under its actual cooling conditions.
