Broadcast applications such as 5G require high quality resonators in order to be able to transmit and receive signals with as little interference as possible. Fraunhofer EMFT offers high-quality, low-noise variable capacity diodes, also known as varactors or varicaps, in small to medium quantities (<2 million units per year). An optimized manufacturing process makes the diodes suitable for high-end applications such as variable capacitance oscillators at GHz frequencies.
