RF Switches are widely used in the operating of signal processing and communication systems. They provide low power and high performance solutions in a wide variety of applications. ADG901BRMZ is one of the most widely used models today and is used for numerous signal processing and communication applications.

The ADG901BRMZ is a surface mount device designed for switching applications that require two operating states: on and off. This type of RF switch handles frequencies from DC to 2.4GHz with an operational frequency range of more than eight octaves. Figure 1 below shows the typical RF switch circuit for a 1x2 series device. The two input signals (RF 1and RF 2) can be combined or split as desired by the user. The control signal (ctrl) operates at a lower frequency and is responsible for the switching action.

Figure 1: Typical 1x2 series RF switch circuitThe ADG901BRMZ is a High Isolation Design switch which isolates the input and output ports at frequencies up to 2.5GHz with typical isolation of 70dB. The device is designed to handle up to 0.5W of power and comes in two package sizes: a 9-Pin MSOP (micro small outline package) and a 14-Pin MLP (micro leadless package). The device has a startup time of 1us and switching time of 3us.

The ADG901BRMZ is suitable for use in a wide variety of applications including wireless communication systems, cellular networks, satellite systems, Wi-Fi networks, GPS receivers, and consumer personal communication systems. The switch is also able to be used in applications that require multiple RF switches to be controlled simultaneously, with the results producing a convenient and efficient signal routing system.

The working principle of the ADG901BRMZ consists of an electrically operated switch that consists of two poles. When the control signal is applied, the two main ports are connected and the signals from the two ports are then merged. The output signal is therefore the combination of both signals from the two ports. When the control signal is removed, the two ports are disconnected and the original signals remain independent.

The ADG901BRMZ is an efficient and low power solution for signal switching applications. Its high isolation and wide operating frequency range make this a versatile switch for various applications. The device is available in two package sizes and has a fast switching speed making it suitable for use in many different applications. The wide variety of applications that the ADG901BRMZ can be used in makes this device an excellent choice for signal processing and communication systems.
