RF Switches

RF switches are devices used to control the path of a signal, by routing it from one source to another. The HMC1118LP3DETR is a low power reflective RF switch that operates from DC to 9GHz. At the heart of the switch lies its single-pole, double-throw (SPDT) structure which provides excellent linearity, low insertion loss and high isolation, resulting in superior switching performance even at high frequencies.

Application Field

The HMC1118LP3DETR is suitable for a wide range of applications, in both commercial and military products. Examples include low power communication systems, such as point-to-point radio equipment, and radar systems. It is also used in frequency-hopping transmitters and receivers.

Working Principle

The HMC1118LP3DETR switch works on the principle of electromagnetism. The user provides a control signal to the switch which closes an internal contact, altering the path of the signal. This is done through the use of specialized materials, which when subjected to an electric field, become magnetized and therefore act as a barrier. In this way, the switch can move between two different states, allowing only one of the two signals to pass.

Furthermore, the use of transient reflection suppression enzymes allows the switch to operate accurately even when extreme pulses of electricity are used. This ensures that the switch can handle high power signals as well as low power ones, making it highly reliable for a wide range of applications.

In conclusion, the HMC1118LP3DETR is a highly reliable and durable RF switch, thanks to its excellent linearity, low insertion loss and high isolation. Its unique single-pole, double-throw structure allows for accurate high power switching, making it suitable for a wide range of military and commercial applications.
