RF switches are extensively used for wireless communication devices such as cell phones, wireless networks and GPS receivers. The SKY85605-11 is a high-power RF switch, which can support switching linearities of up to 10 dB over its operating range.

Application Field

SKY85605-11 is ideal for applications requiring a high-power RF switch with minimal power consumptions. It can be used for applications like broadcast transmitters, amplifiers, antenna tuning, amplifier switching, signal switching and antenna switching. It is also suitable for applications requiring high isolation, low insertion loss and fast switching speed.

Working Principle

The SKY85605-11 switch utilizes a bidirectional PIN diode-based switching circuit to ensure high performance. It operates by placing a DC voltage on the PIN diode, which causes a current to flow through the PIN diode. This current then acts as a variable resistive element in the signal path. This in turn allows the switch to be used as a variable attenuator or amplitude modulator. The switch can also be used to isolate one path from another, allowing one signal path to be completely isolated from another.

The switch also incorporates a high-power RF detector, which is critical to ensure fast and accurate switching. This detector is capable of detecting signals up to 18GHz, and can provide a fast response time of 10 ns. The detector also features a 10 dB signal-to-noise ratio, meaning that it can accurately determine the presence or absence of a signal.

In addition, the switch has an integrated RF switch driver circuit, which provides a robust and reliable signal switching. This circuit provides high isolation between signal paths, preventing intermodulation products from occurring. It also offers low distortion operation, lower power consumption and improved signal linearity over a wide operating temperature range.

Overall, SKY85605-11 is an excellent high-power RF switch that can be used in a variety of applications. It is highly reliable and offers high isolation, low insertion loss and fast switching speeds.
