Radio Frequency (RF) switches are important components in a number of electronic devices, where they are used to select which of multiple frequencies/signals will be routed through one or more components in a system. The ARV20N4HQ is a very versatile RF switch suitable for both military and civilian applications. In this article, we will look at the application field and working principle of the ARV20N4HQ.

The ARV20N4HQ is an intermediate-frequency (IF) switch designed for high-frequency applications. It has an operating range from 5MHz to 2.5GHz, making it suitable for a wide range of radio applications, including mobile phones, radio links, satellites, and aviation. The ARV20N4HQ is capable of handling up to 40W of power, meaning it can provide reliable performance even in highly demanding conditions.

The working principle of the ARV20N4HQ revolves around its special switching element – the Gunnplexer. A Gunnplexer uses a combination of an active amplifier and Gunn diode to modulate the signal, which results in very low impedance and high dynamic range. The Gunnplexer switch in the ARV20N4HQ is capable of achieving switching times of 0.4µs, making it suitable for high-speed applications such as MHz to GHz frequency hopping.

The ARV20N4HQ is a very robust switch, thanks to its hermetically sealed construction and triple-stage insulation system. It also supports a wide range of control input formats, meaning it can be integrated easily into an existing system. In addition, it has a wide voltage range (7.5V to 28V) and low power consumption, making it suitable for battery powered systems.

Overall, the ARV20N4HQ is a very versatile RF switch suitable for a wide range of high-frequency and high-speed applications. Its robust construction, wide voltage range, and low power consumption make it suitable for military and civilian applications. Its unique Gunnplexer switching element helps it achieve very fast switching times, making it an ideal choice for frequency hopping applications.
