After graduating from Queen’s University Belfast with a PhD in high-frequency electronics, Dr Jonathan Leckey has worked for 25 years as an integrated circuit (IC) designer. He has noted an increased demand for higher data rates in mobile and satellite communications, and that system designers are choosing to operate at the undeveloped millimetre wave (mmWave) frequency bands where larger signal bandwidths are accessible. This has created a need for a new generation of mmWave transmit-and-receive solutions, which Jonathan is ready to fulfil.
Jonathan founded MMIC-LAB Ltd in order to develop a range of mmWave front-end ICs to address the growth in both communication devices and radar sensors. At the moment there aren’t sufficient high-performance devices that can provide enough linear power and low noise in these bands. His company’s answer is a chip-scaled package (CSP) format in the 50 to 100GHz range using gallium arsenide fabrication processes with CSP options.
The initial proof of concept designs are nearing completion. The results have shown advantages in power and efficiency, lower assembly costs, improved environmental ruggedness, and high volume assembly compatibility.
Jonathan joined the Regional Talent Engines programme in 2022. He says: “The scheme has been extremely useful in providing financial support and an objective validation of my idea. This has given me increased confidence when dealing with potential partners and in putting together funding applications.”
Now, Jonathan is conducting product development of both a 120GHz radar sensor and initial transmit-and-receive MMICs for the mmWave market. He is also overseeing the perfecting of his CSP technology, which, he feels, will provide a unique selling point for his company’s MMIC products.
