RF Switches are electronic switching devices used to select one signal path from many available paths. These switches are typically identified by the number of paths they have, ranging from two paths (duplexer) to an unlimited number of paths (matrix switch), and frequency ranges they are capable of handling. The RF5500 switch is a monolithic CMOS, full-duplex (2-path) switch for low-loss RF signal routing. This switch is designed for switching analog and digital RF signals and can handle RF signals up to 1.65GHz. It also has many application fields and a working principle which is described below.

Application Field

  1. Modern microwave radio for cellular, PCS, and digital trunking systems.
  2. RF switching for tunable digital filters, antennas, couplers and other RF components.
  3. AM, FM and TV receivers.
  4. In-line multimedia systems using filters, VCOs, multiplexers, switches, and attenuators.
  5. RF interfaces.

Working Principle

The RF5500 switch works on the principle of using a charge pump, a low pass filter, a pair of CMOS digital switches, and a linear controller to control the analog signals. The charge pump operates on the principle of transferring charge from one capacitor to another in order to create a control voltage, which is used to activate the CMOS switches. The low pass filter is responsible for reducing noise and ripple that might otherwise occur in the switching process. The pair of CMOS digital switches form the RF switch itself. The first switch is responsible for switching between the two paths, and the second switch is responsible for switching between the four possible input/output states. The linear controller is used to control the activation and deactivation of the RF switch in order to ensure that the desired signal path is selected.

The RF5500 switch offers low insertion loss and high linearity performance over the frequency range it can handle, making it an ideal choice for applications that require good signal routing capability. It is also pin compatible with many other RF switches, which makes it an easy-to-use, cost-effective solution.

In summary, the RF5500 switch is an ideal choice for applications that require good signal routing in frequency ranges up to 1.65GHz. It offers low insertion loss and high linearity performance and is pin compatible with many other RF switches, making it an easy-to-use, cost-effective solution. The switch works on the principle of using a charge pump, a low pass filter, a pair of CMOS digital switches, and a linear controller to control the analog signals.
