RF Switches have a wide range of applications, from cellular, Wi-Fi, and radar applications, to signal switching and digital television applications. The HMC536MS8GE is an important family of RF switches that have become popular in the industry for their high switching speed and low distortion characteristics. This article outlines the application fields and working principle of these RF switches.

Application Fields

The HMC536MS8GE switches are ideal for applications that require low signal distortion and high switching speed. These RF switches have been widely used in cellular phone designs as a result of their excellent signal integrity in the low range of frequencies. They are also used in Wi-Fi and broadband applications as they are capable of maintaining excellent performance over the 2.4GHz to 18GHz frequency range. They are also popularly used in dynamic power control of certain system components, such as amplifiers, and have also gained popularity in digital television applications, such as in the switching of RSSI signal feeds.

Working Principle

The HMC536MS8GE switches use a DP2T switch configuration in order to provide high signal integrity in a wide frequency range. The DP2T stands for Dual Pole, 2 Throw, which refers to the switch configuration. This means that the switch has two separate poles, each capable of switching two possible output connections. In other words, the switch is capable of switching between four possible output configurations. This allows for great flexibility when setting up a network as it is possible to select different routes for signals depending on the output configuration chosen.

The two key features of the HMC536MS8GE are the low signal distortion and high switching speed. The low signal distortion is made possible by setting up an RF reflection cancellation scheme. This allows for low insertion loss and high isolation between the input and output signals. The high switching speed is achieved through the use of an Internal Tracking Switch (ITS) output driver. The ITS output driver allows the switch to switch between the four output configurations quickly and without any delay.

In addition, the switch features a high linearity characteristic, making it suitable for applications that require low distortion of the input signal. It also features low spurious signal generation, meaning that the output signal does not contain any signals that do not originate at the input side of the switch. This ensures that signal integrity is maintained in the output signal.

Conclusion

The HMC536MS8GE is an important family of RF switches that have become popular in the industry for their high switching speed and low distortion characteristics. These switches are ideal for applications that require low signal distortion and high switching speed, such as cellular, Wi-Fi, and radar applications, as well as signal switching and digital television applications.
