This application note explains how a 40-67 GHz 1W wideband mmWave amplifier can be used when frequency coverage is more important than high output power. The CorelixRF CRF-PA-40000M67000M-1W gives engineers a GaN SSPA option for broadband high-frequency test chains, component validation, communication hardware evaluation, and other authorized RF engineering setups.
The model covers 40 GHz to 67 GHz and uses 1.85 mm female RF input and output in a compact small-unit configuration. A 1 W output level is not meant to replace high-power V band rack systems. Its role is more practical: add controlled power after a source, converter, or driver when a test needs broad mmWave span, manageable hardware, and a repeatable RF path. CorelixRF’s high frequency RF capability page provides relevant context for this type of requirement.
Application scenario: broadband component evaluation
Many high-frequency components are evaluated across a wide band rather than at one fixed point. Filters, mixers, switches, converters, waveguide transitions, antenna-feed parts, and subsystem inputs may need enough power to expose behavior that a low-level source alone cannot show. A 40-67 GHz 1 W amplifier can help raise the available level while keeping the bench more compact than a rack-class high-power amplifier.
Recommended test-chain structure
- Start with the signal source or upconverter and verify clean output across the planned frequency points.
- Add a controlled attenuation stage so the amplifier input level stays within the reviewed operating range.
- Use high-quality 1.85 mm cabling and connector practice for the input path.
- Place measurement couplers, sensors, loads, and protection hardware where the data will represent the actual device condition.
- Record output power, gain trend, thermal behavior, and any alarm or protection state during the sweep.
For data planning, CorelixRF’s RF testing and validation workflow is a useful internal reference. The amplifier should be evaluated as part of a measurement chain, not only as a standalone power device.

Why 1 W may be the right output class
In some labs, higher power adds cost, size, heat, and safety planning without improving the measurement. A 1 W amplifier may be enough when the main issue is source loss, fixture insertion loss, or broadband device drive level. It can also serve as a driver stage before a later high-power amplifier. If a project requires more output at similar frequencies, compare the need with CorelixRF’s 18-40 GHz amplifier category and upper-mmWave options.
Integration notes
The RFQ should define the exact frequency span, power required at the device input, waveform, duty cycle, input level, cable length, connector plan, cooling environment, and measurement method. CorelixRF’s engineering and manufacturing page can help technical buyers understand how RF, mechanical, thermal, and validation considerations connect during project review. For educational follow-up, the RF amplifier blog can support internal linking around amplifier selection and test planning.
