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.

What We Need to Check the Right Attenuator

Model-specific values are confirmed after the configuration is selected. Send the items below instead of guessing from a general product range.

Operating Frequency

Start and stop frequency, plus any sub-band that must remain within specification.

Attenuation Requirement

Nominal dB value and any accuracy or flatness requirement that matters in your RF path.

Power Conditions

Average or CW power. For pulsed systems, also provide peak power, pulse width and duty cycle.

Impedance & VSWR

Required system impedance and the VSWR limit if your design has a defined acceptance value.

Connector Arrangement

Connector series, male/female interface and input/output arrangement required by the existing line.

Mechanical Limits

Maximum envelope, mounting method, installation space and thermal constraints that affect the build.

Fastest Way to Start

Already Have a Part Number, Drawing or Datasheet?

Send it with the required quantity and operating conditions. We can use it as the starting point for the configuration review.

Order Review

What Happens After You Send the Requirement

The goal is to remove interface and specification ambiguity before the order is finalized.

01

Requirement Check

We review the operating band, attenuation, power and requested interface.

02

Configuration Match

We match the electrical and mechanical requirement to the available configuration.

03

Technical Confirmation

Available technical documentation is provided for confirmation before final order placement.

04

Order Support

Any agreed connector, dimensional or documentation details stay tied to the selected configuration.

Send frequency + attenuation + power + connector type.

Practical RF Details

Details That Prevent the Wrong Configuration

These details are useful when the attenuator must replace an existing part or fit into a fixed RF assembly.

Existing Part Reference

Manufacturer part number, label photo or existing datasheet.

Connector Detail

Series, gender and any adapter currently used next to the attenuator.

Installation Envelope

Available length, diameter/width, mounting clearance and cable direction.

Operating Conditions

Ambient temperature or other environmental limits when they affect the requested build.

Quantity

Prototype quantity, production quantity or expected repeat requirement.

Required Documentation

Tell us what technical or order documentation must be reviewed before purchase.

Before You Place the Order
Ask us to confirm the RF and connector configuration.
A drawing or current part number usually makes the review faster and clearer.

Order Questions

Quick Answers Before You Inquire

What information should I send for a quotation?

Send frequency range, attenuation, power, impedance, connector type/gender, mechanical limits, quantity and any required documentation.

Can I send an existing part number or drawing?

Yes. A current part number, datasheet, label photo or drawing can be used as the starting reference together with your operating conditions.

Are all electrical values fixed across the product family?

No. Frequency, attenuation, power, connector and mechanical values depend on the selected configuration. Confirm the final values against the applicable technical documentation.

What warranty does Dolph publish?

Dolph Microwave publishes a one-year warranty from the date of delivery for defective material and workmanship, subject to its stated warranty terms.
