TORONTO, June 17, 2024 -- Per Vices Corporation, a leading provider of software defined radios (SDRs), is pleased to announce the release of Calamine, the company's latest and widest tuning range SDR. This release builds on the impressive product line already established and integrated into mission critical systems for the defense, GPS/GNSS, communications, and test and measurement markets. Calamine builds on the Per Vices existing IP to offer an impressive tuning range from near DC to 40 GHz with four (4) independent receive radio chains each offering 300 MSPS sampling bandwidth.

Software-defined radio (SDR) can assist with the integration and use of radar as it is used in electronic warfare (EW) systems and give users the flexibility to adapt to modern and constantly evolving threats.

It is no surprise that GPS/GNSS [Global Positioning System/ Global Navigation Satellite System] is remarkably important in modern society, with applications ranging from mobile phones to missile guidance systems. Particularly in the military, these signals can often dictate the difference between life and death. Therefore, modernization of GPS equipment and techniques has been a natural process following years of technological advancements in RF technology. One of the main achievements in this field was the development of M-codes, which provide a more reliable, secure, and flexible GPS source for military receivers. M-codes can improve GPS applications in the military – let’s look at the role software-defined radios (SDRs) play in this industry.

The main structure of a 5G network is the radio access network (RAN), which can be implemented in several architectures. Regardless of the architecture, software-defined radios (SDRs) play a major role in every step of the RAN chain, including backhaul, midhaul, and fronthaul. SDRs – whether on the battlefield or the urban jungle – provide important technological features that handle the “big data” glut, including fast 10-100 Gb/sec fiber communication, wide tuning range, several multiple-input/multiple-output (MIMO) channels, high phase coherency, and a software-based backend that can be programmed to fit any applications.

As wireless technology has gradually become cheaper, its use among the general public has grown. As a result, the amount of signals operating in the radio band increases, causing congestion. Interference can occur due to internal, external, and malicious sources; internal interference is unintentional and caused by an organization’s own devices, while external interference – cochannel or crosstalk, spurious signals, or natural occurrences like solar flares – is out of the organization’s control. The danger from interference arises when the radio-frequency (RF) operations – especially government-regulated bands allocated for defense-related, mission-critical, life-critical, and emergency services – are too full to handle the signals. The solution: Software-defined radios (SDRs), which are capable of enforcing spectrum policy and removing interference from the allocated frequency bands by incorporating a number of suitable strategies.

Radio technology is and will continue to be an indispensable part of communication systems, particularly those used by the military. Software-defined radios (SDRs) have significantly reduced the cost of satellite systems while exponentially increasing their functionality, efficiency, and durability.
