Looking to the future

Quantum computing: solving complex challenges

The microwave circuits in quantum computers operate at superconducting temperatures, and are particularly sensitive to electromagnetic interference. Filtronic has developed advanced microwave filters to overcome this critical problem. RF technologies offer further potential to solve some of the unique challenges associated with quantum computing.

Defence – securing critical communications

In defence applications, unreliable or interrupted signals caused by congested frequency bands could cost lives. Moving up to E-band not only offers higher data rates, but also provides more directional signals that are harder to intercept. Alongside this, there is a push towards more digital signal processing in the radar signal chain. New technologies in the pipeline include ultrawide band (UWB) tuneable filters, operating across a broad spectrum of frequencies, which will be used to capture highly accurate spatial and directional data.

Telecoms – make space for data

To manage forecasted data traffic, millimetre wave (mmWave) bands at the higher end of the frequency spectrum will need to be licensed for use by telecoms. The semiconductor processes and RF technologies required for W-band (92-115GHz) are well advanced – and will be ready by the time licences are granted. Work is underway to solve the fundamental challenges associated with D-band (138-174GHz), which offers much higher data rates, but requires significant changes to device architecture and manufacture.
