RF Switches

RF switches are active components that are used in radio frequency (RF) applications. They have the ability to switch signals between two or more ports, and can also be used to isolate signals from other electronic components. The SKY13374-397LF is one such RF switch and has been specifically designed to meet the stringent requirements of the wireless industry.The SKY13374-397LF is a two-pole 2.4GHz SPDT (single-pole-double-throw) switch with an input and output impedance of 50 ohms. The switch is capable of handling a maximum power of +50dBm with an insertion loss of only 0.2dB. This makes it an ideal candidate for use in 802.11b/g/n Wi-Fi applications. It has an operating frequency range between 2400-2500MHz, and is constructed using a dual gold-plated thick film ceramic structure. This makes the switch resistant to shock, vibration, and temperature fluctuations, making it suitable for use in harsh environments.The SKY13374-397LF is widely used in applications such as wireless routers, wireless access points, point-to-point radios, and remote radio heads. Due to its high signal-to-noise ratio, it is also well-suited for use in GPS applications.The working principle of the SKY13374-397LF is relatively simple. When there is no power applied to the switch, it is in a ‘floating’ state which means that the port connected to the internal resistor is isolated. When the switch is excited by a small DC voltage or current, the internal resistor is shorted, allowing a signal to pass through the port. This is a standard single-pole-double-throw configuration, so the signal could be passed to either port depending on the state of the switch.The SKY13374-397LF is also a highly reliable switch and has a superior long-term reliability record. It is designed with a low gate switch capacitance of only 0.9pF. This low gate capacitance ensures that the switch operates at a much faster switching speed and a much higher isolation as compared to other RF switches.Overall, RF switches are essential components used for a wide range of applications, and the SKY13374-397LF is an ideal choice for a variety of RF applications. Its ultra-low power consumption, wide operating frequency range and superior reliability make it well-suited for use in various wireless applications.
