Microwave Generators for MPCVD & Diamond Growth
SDACME supplies 6 kW, 10 kW and 15 kW 2450 MHz microwave generators for MPCVD, diamond growth equipment and OEM microwave plasma integration. Generator selection is evaluated together with the chamber, microwave transmission path, matching conditions, cooling, control interface and the requirements of the complete system.
15 kW 2450 MHz Microwave Generator
Example microwave-source configuration for MPCVD, diamond growth and OEM microwave plasma equipment requiring a 15 kW-class 2450 MHz generator.
Final generator selection and supply scope are confirmed according to the chamber, microwave interface, matching, cooling, control requirements and the complete MPCVD system configuration.
How the Microwave Generator Fits into an MPCVD System
The microwave generator is the energy source of the MPCVD microwave chain, but it does not operate in isolation. Microwave energy must be transmitted, matched and coupled into the chamber under conditions suitable for the complete plasma system.
Microwave Generator
Provides the controllable industrial microwave source required by the MPCVD equipment.
Transmission Path
Transfers microwave energy from the source toward the process chamber through the project-specific microwave arrangement.
Matching & Coupling
The generator, transmission path, chamber and plasma load must operate as a coordinated microwave system.
MPCVD Chamber
Chamber, vacuum, gas and process conditions determine the actual plasma and deposition environment.
Microwave generator power should therefore be evaluated together with the chamber, microwave interface, matching conditions, cooling and control requirements rather than as an isolated kW value.
6 kW, 10 kW and 15 kW Microwave Sources for MPCVD
SDACME's current 2450 MHz range includes 6 kW, 10 kW and 15 kW microwave generators for MPCVD, diamond-growth, plasma and OEM equipment-integration projects.
6 kW MPCVD Microwave Source
A 6 kW-class industrial microwave source for applicable MPCVD, plasma and research-equipment integration.
- Confirm chamber and load conditions
- Confirm microwave interface
- Confirm cooling and control requirements
10 kW MPCVD Microwave Source
A medium-power 2450 MHz source for applicable MPCVD, microwave-plasma and OEM equipment projects.
- Confirm existing or target power
- Confirm transmission arrangement
- Confirm control and cooling conditions
15 kW MPCVD Microwave Source
The higher-power option in the current 2450 MHz range for applicable MPCVD and OEM microwave-plasma equipment.
- Confirm chamber and plasma load
- Confirm matching and interface conditions
- Confirm cooling and control integration
For replacement projects, the existing power class is a useful starting point. For new equipment, the generator should be evaluated together with chamber, microwave interface, matching, cooling and control requirements. Higher microwave power alone does not determine diamond output or material quality.
How to Select a Microwave Generator for MPCVD
Start with the complete MPCVD equipment conditions rather than choosing a generator from the kW rating alone.
Frequency & Power Class
Confirm the required frequency together with the existing or target microwave power. This page focuses on the current 2450 MHz 6 kW, 10 kW and 15 kW range.
Chamber & Plasma Conditions
Chamber geometry and plasma operating conditions affect how the microwave source interacts with the complete MPCVD system.
Waveguide & Transmission
Confirm waveguide size, flange/interface information and the existing microwave transmission arrangement before finalizing the source.
Control & Cooling
Define local or system-level control, communication requirements, cooling conditions, operating mode and the required integration boundary.
A suitable MPCVD microwave source matches the generator to the equipment architecture and operating conditions—not simply to a requested power number.
From Generator Only to an OEM Microwave Subsystem
MPCVD manufacturers and integrators do not all need the same supply scope. The microwave-side package can be defined around what is already available in the customer's equipment.
Generator Only
For customers who already have the required microwave transmission, chamber and machine-level integration arrangement.
Microwave Generator System
The project can include the generator together with selected microwave-side components according to the agreed system scope.
OEM Microwave Subsystem
For machine builders, the microwave source and related subsystem can be configured around the OEM's mechanical, cooling and control interfaces.
Example of microwave-side equipment connections used when reviewing cooling and integration requirements.
Reflected Power, Matching & Plasma Stability
An MPCVD plasma chamber is not simply a fixed load. Microwave operating conditions can change with the plasma state and the complete system, so reflected power and matching must be considered at system level.
Reflected Power
Reflected microwave energy indicates that part of the transmitted energy is not being absorbed by the load under the current system condition.
Matching Conditions
Matching components help establish suitable energy transfer between the microwave source, transmission path and process load.
Plasma Stability
Stable microwave generation is one part of maintaining a usable plasma condition. Chamber, vacuum, gas, pressure and process settings also matter.
Matching, tuning and protection requirements are confirmed during technical integration according to the selected generator and complete MPCVD system configuration.
Control, Monitoring & Cooling Integration
The microwave source must operate as part of the overall MPCVD equipment control and utility system. The exact interface scope depends on the selected generator and project configuration.
Control
Local operation or communication with the customer's equipment controller can be reviewed according to the selected configuration.
Monitoring
Applicable generator operating information can be made available according to model and agreed project scope.
Interlock Boundary
The MPCVD equipment and microwave generator require a clearly defined safety and equipment-interlock boundary.
Cooling
The current 2450 MHz generator range uses external water cooling. Requirements remain model- and project-specific.

Frequently Asked Questions
Common questions about selecting and integrating a microwave generator into MPCVD and diamond-growth equipment.
What microwave frequency is used for the 6–15 kW MPCVD range?
The current 6 kW, 10 kW and 15 kW range covered on this page uses 2450 MHz. Final selection should still be checked against the actual MPCVD system.
Which microwave generator power should I choose?
For a replacement project, begin with the existing generator. For new equipment, evaluate power together with chamber, load, microwave interface, cooling and control requirements.
Can I buy only the microwave generator?
Yes. Projects can be discussed as generator only, microwave generator system or OEM subsystem depending on what equipment is already available.
Can SDACME supply microwave-side components?
Selected microwave-side components can be included according to the agreed generator configuration and project supply boundary.
Why is reflected power important in MPCVD?
Reflected power is related to how microwave energy is transferred between source and load. The operating condition depends on generator, transmission, matching, chamber and plasma state together.
Does higher microwave power mean faster diamond growth?
Not by itself. Diamond growth rate, output and material quality depend on the complete equipment and process conditions, including chamber, plasma, gas, pressure, substrate and process settings.
Can the generator communicate with my MPCVD controller?
Control and communication capability depends on the selected generator and project configuration. Include the required control method and interface in your RFQ.
Do you also supply complete MPCVD equipment?
Yes. Customers requiring complete equipment rather than only the microwave source can continue to the dedicated MPCVD machine page.
