Radio Communication

Air Traffic Control introduced digital standards VDL. However, due to the inertia of the air traffic industry, the use of the old-fashioned AM modulation has not ended yet.

Many other radiocommunication segments adopted wide bandwidth digital modulations, often based on OFDMA and QAM. Such bandwidth requirements and modulations bring high demands on transmitter linearity due to their high crest factor.  

The use of 5G and 6G cellular networks brings radio frequency bands around 27 GHz for short ranges and V2X standards.  

Satellite communication in Ku-Band 12–18 GHz is used in niche markets.

• We can offer our extensive engineering skills.
• We provide services from the initial concept to the production of the first product series.
• Our hardware engineers are experienced in integrating their prototypes with our internal software.
• They are ready to closely cooperate with our firmware engineers or with your part of the team if required.

Around 2003, we started developing the air traffic control (ATC) radio family for one of the top world producers. We led it through all development phases, including concept, design, certification, and manufacturing start. 

We went through the development of a TETRA base station for another world leader in that application area a few years later. We developed amplifiers for the transmitter block (which is unique), HAL application for the embedded Linux software, and an FPGA signal processing block that took care of signal filtering and modulation/demodulation.

The most recent focus

During the last five years, we have been engaged on the Internet of Things, where especially the radio parts like WiFi, LTE, LoRA, NFC, and Bluetooth, are relevant to radiocommunication. 

The second segment we are focusing recently is radio monitoring instruments and antennas for the bands up to 50 GHz. We are still going further to the next higher bands.
