ADG936BCPZ-R

RF Switches

An RF switch is a device that can open, close or provide a signal path between two ports under the control of an external signal, operating at frequencies up to the GHz range. It is used to select the path for the signal and to control the signal direction from one circuit stage to another. One of the most common uses of RF switches is for frequency selection in a receive system or transmitter antenna selection.

ADG936BCPZ-R application field and working principle

The ADG936BCPZ-R is an analog single-pole double-throw (SPDT) switch manufactured by Analog Devices. It has a maximum frequency of 9 GHz, and is used in a wide range of applications, such as for frequency selection in a receive system, or antenna selection in a transmitter. It has a typical on-state insertion loss of <0.15 dB, with a maximum on-state loss of 0.25 dB. The off-state isolation is typically 17 dB, with a minimum of 10 dB. The on-state switch time is typically 250ns, and the off-state switch time is typically 50ns.

The ADG936BCPZ-R operates on supply voltages of +3.0 V and -0.3 V, with a current consumption of 3 mA. It can control up to four ports with a single device, with the control signals being either logic or RF-compatible. This makes it ideal for applications where a single control line is used for multiple switches. The RF lines feature high-impedance states, which makes them compatible with both logic and RF devices.

The ADG936BCPZ-R has a typical operating temperature range of -55°C to +85°C, making it suitable for harsh environments. It is available in a leaded package of 0.5mm x 0.5mm or lead-free package of 0.3mm x 0.3mm, with an MSL rating of 3A. It can also be soldered in the surface mount reflow process.

In conclusion, the ADG936BCPZ-R is a highly versatile switch suitable for a range of applications. Its high frequency range, low on-state insertion loss, and high off-state isolation make it suitable for use in high-performance signal processing applications. The ability to control up to four ports with a single device also makes it ideal for applications that require multiple switches in a single package.
