CML Micro Unveils 2W GaAs Power Amplifier to Simplify UHF System Development

CML Micro has expanded its SµRF range with the release of the CMX90A006, a 2W power amplifier designed for sub-GHz applications in wireless transmitters. This amplifier promises to enhance the performance and reliability of ultra-high frequency (UHF) systems, targeting industrial, scientific, and medical (ISM) and short-range device (SRD) bands.

The CMX90A006 is optimized for the 868 MHz (SRD) and 915 MHz (ISM) bands, delivering an impressive +33 dBm output power at 1 dB gain compression across a broad 860 to 930 MHz frequency range. This makes it a versatile solution for various license-free band applications, such as UHF RFID readers, smart metering technologies, and IoT wireless devices.

Engineered for reliability and linear performance, the CMX90A006 leverages indium gallium phosphide (InGaP) heterojunction bipolar transistor (HBT) technology. It offers a power-added efficiency (PAE) of 52%, a small signal gain of 33 dB, and a third-order intercept (OIP3) of +42 dBm at 26 dBm per tone. This combination makes it ideal for systems requiring high power efficiency and low signal distortion.

Key Product Features:

  1. Wide Voltage Range: The CMX90A006 operates across a supply voltage of 2.5 to 5.25V, offering system-level flexibility. It can also be powered by a single-cell Lithium battery, making it perfect for portable, battery-operated applications.
  2. Compact Design: Housed in a 4x4 mm thermally enhanced Very-thin-profile Quad Flat No-lead (VQFN) package, the amplifier integrates seamlessly into space-constrained designs.
  3. Simplified System Integration: The RF input port is internally matched to 50 Ω, minimizing the need for additional components and streamlining system design. CML also provides the EV90A006 evaluation board, which includes an output matching network, to help engineers optimize performance for specific applications.

According to Arwyn Roberts, RF Product Manager at CML Micro, “The CMX90A006 represents a significant advancement in our sub-GHz SµRF range, offering engineers a power amplifier that not only delivers robust linear performance but also ensures high reliability for critical ISM band applications. Its ability to operate across a wide voltage range and deliver high efficiency makes it an ideal choice for the latest UHF RFID readers, smart metering technologies, and a host of other battery-operated IoT wireless devices.”
