The ARD22012Q RF Switch is designed for operations in professional, medical communications, embedded wireless device applications, Wi-fi/Bluetooth technology, and many other wireless or telecom infrastructure applications. This switch offers superior RF isolation and excellent RF accuracy of 1.8dB insertion loss and 0.5dB of maximum return loss. It supports a broad operating frequency range spanning from 18 MHz to 250 MHz and is suitable for both 50Ω and 75Ω systems.

The ARD22012Q RF Switch is composed of an array of low resistance MEMS switches, which are designed to provide bidirectional switching capacity. The switches have an ultra-low resistance of 0.3Ω and are capable of achieving high isolation of at least 60dB. The high isolation ensures excellent RF performance and excellent signal rejection from other signals. Furthermore, the switches are designed to operate over a wide temperature range, from -40°C to +85°C.

The ARD22012Q RF Switch integrates a low noise charge pump for the RF signal switching and provides power and control for the switches. The charge pump is designed to provide low noise and optimal performance in RF environments. Furthermore, the charge pump can also transfer the RF signals in a bidirectional manner without any interference or noise. In addition, the RF switches are designed with a low-loss integrated circuit design and have a good linearity with respect to the input signal.

The ARD22012Q RF Switch has a unique feature of auto-calibration. This auto-calibration adjusts the output control signals and ensures a more accurate working of the RF switches. Furthermore, the switches are designed with a fast response time of 2 to 10 microseconds and are capable of switching quickly and accurately. The RF switching speed can also be controlled remotely, allowing for precise adjustments of the switching speed with just a few clicks.

The ARD22012Q RF Switch is built with advanced digital filter technology to reduce spurious noise and interference when switching the signal. The digital filter technology ensures a clean and consistent signal, providing a better performance for the equipment. Furthermore, the switches also feature an adjustable threshold voltage, which can be configured to reduce false switching and improve the overall signal quality. In addition, the switches are designed with an integrated ESD protection feature to protect the terminal contacts from any static electricity.

The ARD22012Q RF Switches are an excellent choice for various wireless infrastructure and communications applications. These switches offer excellent RF performance with superior RF isolation, low noise charge pump design, and fast switching speed. The auto-calibration feature helps to provide more accurate switch operations and the digital filter technology ensures a clean signal output. Additionally, the adjustable threshold voltage helps to reduce false switching and the integrated ESD protection keeps the terminals safe from static electricity. All these features offer superior performance in wireless and wireless infrastructure applications.
