.RF Switches are widely used in a variety of applications, from simple support for connecting two or more devices, such as antennas, to more complex systems and applications that require accurate control and flexibility. The BF1118W-115 is a single switch with an ultra-low-power CMOS hysteresis logic that works on 3-14 and 13.2 VDC supplies, making it suitable for most applications. It also features low switch-on and switch-off times as well as a host of other features. In this article, we will explore the application field and working principle of the BF1118W-115.
Application Field of BF1118W-115
The BF1118W-115 has a wide range of applications. It is used in Miniature mobile base station systems, such as 3G, WiMax and GSM, for bridge, antenna switch control and routing switching. It is also suitable for Wi-Fi networks, GPS navigation systems and satellite communications as well. Furthermore, it is suitable for high-end mobile phone handsets and other portable and embedded applications.
Furthermore, the BF1118W-115 is used in cellular femto, pico and microcell base stations, for bridge switching, directional couplers, GPS, PCS, 3G cellular, WLAN, WiMax/LTE, cellular repeaters, satellite communications, RF amplifiers, antenna switching, RFID and other applications. It is also used in automotive, aerospace, military and medical applications.
Working Principle of BF1118W-115
The BF1118W-115 utilizes an ultra-low-power CMOS hysteresis logic to drive the RF switches. The logic operates in two states: a “low” state and a “high” state. When the logic is in the “low” state, the switch is open; when the logic is in the “high” state, the switch is closed. The logic can be further controlled using two control pins, which allow for the switch to be opened or closed via digital or analog inputs.
In order for the switch to open or close, a minimum operating voltage of 3.3 VDC is required. Furthermore, the switch has a turn-on and turn-off time of 1.0µs (with a fall time of 0.3µs), which is much faster than many other switches on the market today. Additionally, the BF1118W-115 features a high switching rate (up to 5MHz) and low insertion loss (up to 0.6dB).
In addition to the open and closed states, the BF1118W-115 can also be used in a bidirectional configuration, and the logic logic can be re-programmed using programming pins. This allows for greater flexibility when dealing with complex applications. Furthermore, the logic logic can be protected using ESD protection diodes.
Conclusion
The BF1118W-115 is a single switch that operates using an ultra-low-power CMOS hysteresis logic. It is suitable for a variety of applications, from Miniature mobile base station systems, cellular femto, pico and microcell base stations, Wi-Fi networks, GPS navigation systems and satellite communications, to high-end mobile phone handsets and other portable and embedded applications. It is also used in automotive, aerospace, military and medical applications. Furthermore, it features low switch-on and switch-off times, high switching rate and low insertion loss. The logic logic can also be re-programmed using programming pins for greater flexibility and can be protected using ESD protection diodes.
