RF Switches

RF switches are parts of electronic circuits that are used to connect or disconnect different parts of an electrical circuit. By switching elements in and out, they allow a device to have multiple functions.

BF1118,215 is a type of RF switch specifically developed for communication applications. It combines a broadband waveguide SPDT switch with a MMIC SP22T switch in a hermetic package.

Application Field

BF1118,215 is well suited for use in transceivers, antennas, microwave test and measurement systems, satellite communications, ISM radios, space diversity systems, base station systems and signal conditioning equipment.

The switch has also found applications in many commercial sectors including aerospace and defense systems, automotive, medical, industrial, instrumentation, telecommunications and wireless communications.

Working Principle

The Broadband RF switch BF1118,215 is based on a waveguide SPDT switch and a MMIC SP22T switch. The waveguide SPDT switch is designed to offer low insertion loss and high isolation over a frequency range of 0.6 - 18 GHz. The MMIC SP22T switch is designed to offer a low insertion loss over an extended frequency range of 0.4 – 8 GHz.

The BF1118,215 switch is a hermetic package which provides an additional measure of protection and prevents contamination of the switch. The switch also features a PIN diode for electrostatic discharge protection, and a PID controller for self-latching control.

The BF1118,215 switch is designed to withstand a high level of current (up to 5A) and voltage (up to 50V). The low-loss characteristics of the switch make it suitable for applications where low noise and low power consumption are important.

Conclusion

The Broadband RF switch BF1118,215 is a reliable and efficient switch for high frequency applications. It offers low insertion loss, high isolation, and a wide range of current and voltage ratings. This makes it a popular choice for a wide variety of applications including communications, aerospace and defense, automotive, medical, industrial, instrumentation, and telecommunications.
