Erzia Mission-Critical RF Converters
Overcoming the challenges of testing and characterising wideband RF Converters
Overcoming the challenges of testing and characterising wideband RF Converters in Electronic Warfare (EW) and Satellite Communication (Satcom) systems is important as poor testing can affect performance, increase costs, and jeopardise mission success. Erzia explores key measurement bottlenecks and examines how modern test equipment and strategic measurement test approaches can dramatically improve testing efficiency and ensure accurate results.
Engineers and technicians testing wideband RF converters face challenges in design, integration, and measurement, all of which are interconnected. While design choices affect measurement complexity, and integration dictates performance parameters, measurement is often the bottleneck. Testing RF converters requires significant time and resources due to the numerous configurations, leading to longer measurement times, complex calibration, and the need for specialised techniques to measure parameters like NF and group delay.
Risks of Insufficient Characterisation
Failing to address efficient characterisation in EW and Satcom systems has serious consequences due to their critical nature:
- Mission Degradation: In EW, poorly characterised converters affect signal processing, jamming, and vulnerability to countermeasures, risking mission success. In Satcom, they reduce signal quality, and data throughput, and can cause link failures.
- Increased Risk and Cost: Delays in characterisation can miss operational windows and lead to costly rework and budget overruns.
- Reduced Performance and Reliability: In EW, converters become more vulnerable to interference. In Satcom, signal integrity is compromised, especially under critical conditions, increasing failure risk.
- Safety and Security Risks: In Satcom, compromised converters can expose communication channels. In EW, inadequate characterisation can endanger personnel in dangerous environments. For engineers and technicians, inefficient characterisation impacts mission success, technological edge, and the safety of infrastructure and personnel.
Practical Approaches to RF Testing and Measurement
The solution to the measurement and characterisation challenge lies in maximising the potential of modern test equipment and using strategic techniques. Advanced instruments like Vector Network Analyzers (VNAs) enable the simultaneous measurement of parameters such as S-parameters, P1dB compression, and Noise Figures, significantly reducing test time.

More Measuring and Testing Solutions
Efficient characterisation of wideband RF converters is essential for mission success, maintaining technological superiority, and protecting critical infrastructure, particularly in demanding fields like EW and Satcom. The main challenges arise from the large number of test configurations and the need for precise measurements. Using modern VNAs (Vector Network Analysers) with strategic measurement techniques provides a clear solution.
