Overview: New Space (NS) demands faster, more affordable, and reliable RF hardware. ERZIA’s New Space COTS amplifiers deliver that balance with 13 launch - ready models.

Key Takeaways:

Quantum computing systems demand exceptional precision in both control and measurement operations. While much attention focuses on qubit coherence and gate fidelities, the RF signal chain that enables these quantum operations requires equally careful engineering. From generating high-fidelity microwave pulses to capturing millivolt - level return signals, amplifiers form critical nodes in the quantum measurement infrastructure.

Electronic warfare (EW) now plays a decisive role in military operations, and the insights shared by those on the ground are directly influencing how the industry sets its priorities. The war in Ukraine has provided unprecedented real-time insights into which capabilities are effective on contested battlefields, prompting military systems to prioritize swift and reliable control of the spectrum.

Military forces have fought for control of land, sea, and air for centuries. Now, a different type of contest unfolds across the electromagnetic spectrum. Unlike traditional combat zones, success here is measured not by territory gained, but by the ability to communicate, detect, and disrupt.

As military operations increasingly leverage space-based assets for surveillance and communications, both performance and reliability of RF and microwave products become defining factors in operational success.

A Competitive and Congested Environment

The NewSpace revolution is transforming satellite technology development and deployment. Satellite manufacturing companies have shown that commercial space ventures can deploy sophisticated satellite communications faster than ever before.
This new landscape requires:

The testing and characterization of wideband radio frequency (RF) converters present significant challenges, particularly for product designers and engineers working on Electronic Warfare (EW) and Satellite Communication (Satcom) systems. Inefficient or inadequate testing can lead to compromised system performance, increased development costs, and even jeopardize mission success.

Traveling-wave tube amplifiers (TWTAs) have traditionally been used in high-power radar systems for meteorology, air traffic control, defense, and maritime services. But now, there is a new technology to consider: solid-state power amplifiers (SSPAs). Gallium Nitride (GaN)-based microwave SSPAs that handle higher power densities, operate effectively at elevated temperatures, and can drive TWTs in high-power radar systems.

With failure not an option, the selection of the appropriate High Power Amplifier (HPA) for aerospace applications warrants consideration of several key factors. HPAs must be able to generate high power levels while maintaining efficiency and reliability, even in harsh environments.

RF and Microwave Mixers play a crucial role in altering signal frequencies within radio frequency (RF) and microwave communication systems. They are essential in various applications, including signal modulation, RF signal demodulation, and frequency conversion in up/down converters.

To optimize system performance, it’s important to understand their key performance metrics and why they matter. Among those are conversion loss and conversion gain.

The Role of a Mixer

The challenges in aerospace technology development are excellent fuel for innovation. For the ERZIA team, it was the strict standard for assembly processes, established by the European Space Agency (ESA), that generated a new method for solving the long-standing problem of QFN thermal cycling.
