5-bit digital step attenuator

25 November 2020 Telecoms, Datacoms, Wireless, IoT

The AM2010, made by Atlanta Micro, is a wideband, 31 dB, 5-bit digital attenuator covering the DC to 30 GHz frequency range in 1 dB steps. The positive control device provides low insertion loss, flat frequency response, and low attenuation error over the operating temperature range of -40°C to +85°C. Packaged in a 4 mm QFN with internal 50 Ω matching, internal decoder circuitry, and drawing less than 2 mA of current, the AM2010 is suited for low SWaP (size, weight and power) applications.

Also available is an evaluation board that includes SMA input and output connectors and an SMA voltage input (unless otherwise requested). The board can also be supplied with a DIP switch for control of the attenuator settings.
