CML Micro Launched Compact Power Amplifier
The CMX90A002 provides a 44 percent reduction in board footprint for IoT and industrial radio applications.
Updated on Oct. 2, 2026 in Consumer Electronics
CML Micro has released the CMX90A002, a power amplifier designed to operate across the 860 MHz to 960 MHz frequency range. This component is now available for purchase through electronics distributors.
Why it matters
The device addresses the industry requirement for supporting diverse power architectures within constrained footprints. By enabling a common platform for various battery technologies, it simplifies design cycles for engineers managing size-sensitive projects.
The device measures 3 mm by 3 mm and supports a wide operating voltage range from 1.9 V to 4.5 V. It facilitates operation within 868 MHz and 915 MHz license-free ISM bands.
The players
CML Micro
A developer of mixed-signal semiconductors specializing in radio frequency and data communication hardware.
The details
The CMX90A002 functions as a power amplifier (a circuit that increases the power of a signal for transmission) that compensates for voltage fluctuations inherent in different battery types. This allows engineers to utilize one standardized platform across multiple products regardless of their individual power architectures. The design shrinks the required printed circuit board (PCB) space, which is the substrate that holds electronic components, by 44 percent compared to previous 4 mm by 4 mm models.
Timeline
October 4 to 9, 2026: The device will be showcased at European Microwave Week in London.
The Tech Race
This release follows a trend of miniaturization in radio frequency front-end components, directly challenging the industry footprint standard of 4 mm by 4 mm. It positions CML Micro to capture more density-sensitive designs in the competitive market for industrial and IoT wireless hardware.
The CMX90A002 is currently available for developers and manufacturers through distributors including DigiKey, Mouser, and RFMW. Design teams can begin integrating the part into new hardware builds that prioritize compact PCB layouts and flexible voltage support.
The takeaway
Designers should track the adoption of this smaller footprint standard as it impacts layout constraints for battery-operated wireless devices. Prospective users should look for technical performance results during the upcoming showcase at European Microwave Week 2026.
