RF Switches are electrical devices that enable the user to switch signals, and also provide isolation, between two sources. Radio frequency (RF) switches are a type of switch specifically designed to handle the higher frequency signals used in radio applications, such as those found in cellular and satellite communications. The AS218-000 is one such high-performance single pole, double throw (SPDT) RF switch. With its wide frequency range, low insertion loss and high isolation, it is well suited to many different RF applications.
The AS218-000 is a highly integrated, crystal-based SPDT RF switch. It is designed to switch between the two antenna ports with a single +3 Volt logic control signal. It is an ideal solution for applications where a high level of performance, size and cost are required. The AS218-000 operates in the frequency range of 0.4 to 6.0 GHz, making it ideal for many applications including cellular phones, gender changers, automotive RF systems, Wi-Fi, satellite, and WiMAX. The insertion loss at 0.4 GHz is 0.7 dB with Rs11 dB of isolation, allowing the device to switch signals between the two ports without the need for any attenuation.
The AS218-000 is constructed using a combination of integrated circuit and discrete components. It features a gold-plated ceramic package with a low profile, and its total height is just 0.25 inches (0.6 cm). This makes the AS218-000 ideal for tight-fitting, multi-application designs. The operating temperature range is from -40°C to +85°C. The AS218-000 is designed to be a self-contained, easy-to-use structure, allowing for quick and easy setup. It also supports both TTL-level and CMOS-level logic control, providing added flexibility for the user.
The AS218-000 is designed for a wide variety of applications, including radio frequency (RF) switching for mobile devices, Wi-Fi, and satellite communications. It can also be used in other wireless devices, such as gender changers and automotive RF systems. Thanks to its wide frequency range and high isolation, it is well suited for use in these environments. In addition, its low insertion loss makes it ideal for switching applications where relatively small signal losses are desired, such as cellular communication.
In terms of its working principle, the AS218-000 utilizes low-voltage USB-level logic control. The voltages which activate the switch are set between two levels: +3V (high) and 0V (low). Once a logic level is applied to the designated control pin, the switch will be activated. The RF signal is then switched between the two antenna ports. The switch is designed to have low insertion loss and high isolation, which reduces the amount of signal loss and unwanted interference. This in turn promotes higher signal quality, greater stability, and minimized cutting-off after switching.
In summary, the AS218-000 is an ideal solution for RF switching in mobile devices, Wi-Fi, and satellite communications. It is a highly integrated, low-profile RF switch with a wide operating frequency range. It can be set up quickly and easily, and its combination of low insertion loss and high isolation makes it ideal for many applications. The AS218-000 utilizes low-voltage logic control to activate the switch, allowing it to switch signals between the two antenna ports without any signal loss or interference. All in all, the AS218-000 is an extremely convenient and effective RF switch solution.
