RF Switches
RF (Radio Frequency) switches allow electrical signals to pass through them in a controlled manner, and are used in a variety of applications. One such switch is the ADG919BRM. This article analyses this particular switch, focusing on its application fields and working principle.
Application Fields & Benefits
The ADG919BRM is a low-voltage, single-pole, double-throw (SPDT) RF switch. It is a high-performance switch with excellent linearity and insertion loss performance. It is designed to operate in the frequency range of DC – 4 GHz. It is suitable for use in a variety of applications including wireless infrastructure, GSM/3G/4G, land mobile radios, radar, Wi-Fi, and many other communication systems. The switch is also equipped with an integrated load save logic,which makes it ideal for space-restricted applications.
Working Principle
The ADG919BRM is a field-effect transistor (FET) based switch. It is fabricated using 45 nm CMOS technology. The switch operates in the voltage domain, and consists of two control inputs: SEL1 and SEL0. These control inputs are used to control the operation of the switch. The switch has two internal states, which can be altered depending on the signals applied to the inputs. When both SEL1 and SEL0 are set to logic 0, the switch is in the OFF state, and a DC block is in place. When either SEL1 or SEL0 is set to logic 1, the switch is in the ON state, allowing the passage of RF signals.
Conclusion
The ADG919BRM is a versatile RF switch with a wide variety of applications including wireless infrastructure, GSM/3G/4G, land mobile radios, radar, Wi-Fi, and many other communication systems. It has excellent linearity and insertion loss performance, as well as a built-in load save logic which makes it ideal for space-restricted applications. Furthermore, it is fabricated using 45 nm CMOS technology and operates in the voltage domain. Weighing all these factors, the ADG919BRM is an ideal choice for any RF switching needs.
