Waveguide Switches
Waveguide switches are electromagnetic switches with hollow circular or rectangular cross-sections and are used for routing RF energy in microwave communications, broadcasting, and in radar applications. Waveguide switches can be used to transfer both power and communication signals, and the bandwidth of a waveguide is in relation to its size, and thus always referred to by its size (e.g. WR112, WR90, WR75 etc.). Compared to coaxial switches, waveguides can route extremely high power signals over a narrow bandwidth at low to high frequencies, and now Lightweight Waveguide series is available.

PWM to Voltage Output D/A Converters
Analog Devices’ pulse-width modulation (PWM) to voltage output D/A converters convert a PWM input to an accurate, stable, buffered voltage without the ripple, slow settling, and external passive components of discrete filter implementations. Our PWM D/A converters measure the period and pulse width of a PWM input signal and immediately update the D/A converter output with up to 12-bit accuracy and no software coding required. This family of D/A converters is available with 8-bit to 12-bit resolution, dual and quad channels, integrated references, and with high temperature operation. Applications include isolated motor control, automotive headlights or industrial lighting, and other applications that benefit from the simple control interface.
