RF switches use signals to switch high-power through a transmission path and are commonly used in multiplexing systems with multiple inputs and outputs. In the field of RF communication, RF switches are used to route or switch radio signals through a circuit, usually between antenna ports of radio transmitters or receivers.PE42420D-Z is a popular RF switch which utilize PIN diode and IC CMOS transmission gate technology. The chip is capable of handling up to+42 dBm (10W) of power, making it one of the most powerful RF switches on the market today. The product contains four SPST load configurations that can be used as individual swtich elements, or in tandem to build a dual-pole double-throw (DPDT) switch.The principle of operation is based on RF PIN diode switching, where the PIN diode is used as a low frequency switch. Simply put, RF PIN diode switching requires a low voltage DC control signal, to modulate the PIN diode bias current. When current is passed through the diode, the diode becomes forward biased and the resistance of the diode drops. When the current is turned off, the diode becomes reverse biased and the resistance increases, thus resulting in a high impedance switch configuation.The PE42420D-Z is commonly used in antenna systems, cellular or cordless telephone systems, repeater systems, and other consumer electronics such as entertainment receivers, as well as military, navigation, and satellite communications. The PE42420D-Z can be applied in systems where higher linearity, isolation and synchronization are advantageous. The device is highly reliable and is also suitable for board-level repairs or changes. it is also compatible with microwave photonics systems, and has been designed for ease of integration.In summary, the PE42420D-Z RF switch is a powerful and reliable RF switch, and is designed for application in multiple RF systems. With its robust design, it is well suited for a wide range of applications, and its efficient design ensures low power consumption and improved performance. The product is a cost-effective solution for customers, and it is highly reliable and easy to integrate as part of an RF system.
