CML Microcircuits is pleased to confirm it will be attending the Live IEEE International Microwave Symposium (IMS) in Atlanta, Georgia, between 7th and 10th June (Booth 1341. Throughout the event, visitors can learn more about the first products in CML’s new SµRF family (Semiconductor Microwave RF). IMS delegates visiting in person can also get up close with the SµRF evaluation modules.

The SµRF family is CML’s range of high frequency, high bandwidth RFICs and MMICs for RF and mmWave applications. The SµRF product family has been designed to help accelerate the design of RF products operating in the mmWave and GHz frequencies. The products being showcased at IMS2021 include:

• The CMX90A003 (1W) and CMX90A004 (2W) 860 – 960 MHz Power Amplifiers. These two-stage, fully matched MMIC power amplifiers deliver +29.5 dBm (CMX90A003) or +32.5 dBm (CMX90A004) of saturated power. Both devices use GaAs HBT technology. The CMX90A003 is ideal as a booster PA in sub-1GHz applications to extend the range of low-power RF transceivers. The CMX90A004 is optimised to operate as a high-power final stage PA in wireless ISM applications.
• The CMX90G301 (+1 dB) and CMX90G302 (+2 dB) 1.4 – 7.1 GHz Positive Gain Slope Amplifiers. These devices are designed to compensate for frequency related gain loss. Using GaAS pHEMT, they combine low DC power, low noise and high gain in a cascadable MMIC.

The CMX90A003 and CMX90A004 Power Amplifiers, and the CMX90G301 and CMX90G304 Positive Gain Slope Amplifiers all follow the SµRF strategy of offering highly integrated solutions that are easy to use. CML’s experts will be available at the event to provide further technical details of the products and target applications.

CML will also be offering visitors the chance to learn more about the recently introduced CMX940 low-power Frac-N RF synthesiser. The CMX940 addresses the demand coming from OEMs for a high-performance, highly configurable RF synthesiser that can operate from 49 MHz to 2040 MHz. It delivers best-in-class phase noise and low levels of spurious products thanks to its high level of integration, which includes a wideband VCO (voltage controlled oscillator).

Due to COVID-19 restrictions there will be no live demonstrations during the in-person event in Atlanta, GA. A video demonstration of the CMX940 will be available, and SµRF evaluation boards will be on display.
