RF switches offer advantages for different types of applications. They can be configured to select the antenna, receiver, or transmitter from a range of options. They can also control the power level of the system or be used for multiple system components. The AMMC-2008-W50 is a single pole eight throw (SP8T) RF switch designed to provide highly reliable signal distribution within 2 - 18 GHz frequency bands.

The specific application fields for the AMMC-2008-W50 switch are mainly satellite communications, wireless networks, medical equipment, navigation systems, and any system requiring a high level of performance. For instance, the high-isolation performance of the switch makes it suitable for use in navigational applications that require a low-noise level and good accuracy.

Working Principle

The AMMC-2008-W50 is designed for use in the frequency range of 2 - 18 GHz with an insertion loss of 1.5dB max, isolation of 80dB min, and input power capability of 30dBm max. It is suitable for medium power applications and for low reflection applications. The switch offers excellent linearity and has the ability to switch fast enough to meet high speed systems.

The working principle of the AMMC-2008-W50 is based on a bridge circuit. This circuit consists of two sets of parallel circuits with their centers connected to each other. When the switch is activated, the output connections of both circuits are combined together to form a single output. This output or combined connection can be routed to the desired port or equipment.

The two sets of parallel circuits are comprised of different types of elements: metal-oxide-semiconductor field-effect transistors (MOSFETs), NMOSFETS, and power diodes. The NMOSFETs are used to handle higher power levels while the MOSFETs take care of very low level signals. The power diodes protect the circuit from high-voltage transients.

The AMMC-2008-W50 switch can be operated in both manual and automatic modes. In manual mode, the switch is operated by an external switch control. This switch control changes the state of the two sets of parallel circuits depending on the command given. In automatic mode, the switch is set to respond automatically to external inputs such as start/stop, power on/off, sensitivity level, and other commands.

Conclusion

The AMMC-2008-W50 RF switch is a highly reliable single pole eight throw switch technology designed for operation in the frequency range of 2 - 18 GHz. It offers excellent performance in terms of insertion loss, isolation, and input power capability and is suitable for medium power and low reflection applications. The working principle of the AMMC-2008-W50 is based on a bridge circuit and can be operated in both manual and automatic modes.
