The 4205B-95.5 from Weinschel by Spectrum Control is a Solid State Programmable Attenuator that operates from 0.3 to 8000 MHz. It has an attenuation range from 0 to 95.75 dB with a step size of 0.25 dB and can handle up to 28 dBm of CW power. The attenuator can be controlled using parallel (TTL compatible), I2C, SPI, UART, or USB interfaces. This RoHS-compliant module is available in a module with SMA (F) connectors and is ideal for use in Automated Test Equipment (ATE), 2G / 3G / 4G LTE / 5G fading simulators, test labs, MIMO, WIMAX, and WiFi applications.
