RFMW Ltd. announces design and sales support for the API Weinschel 4209 series of digital attenuators. Interfacing with popular, high frequency test equipment, the 4209-31.5-1 is equipped with 2.92 mm Female connectors while the 4209-31.5-2 offers 2.4 mm Female connectors.

Both the 4209-31.5-1 and 4209-31.5-2 provide 31.5 dB of attenuation range in 0.5 dB steps and operate from 100 MHz to 40 GHz. MMIC technology offers repeatable performance for uninterrupted RF when changing attenuation values.

 These units can be controlled using parallel (TTL compatible), I2C, SPI, UART, or USB interfaces making them ideal for ATE systems simulating RF fading for 2G/3G/4G LTE and 5G in MIMO, WiMAX and WiFi system design.
