Global RF and microwave components and equipment manufacturer, AtlanTecRF, has launched its latest Ultra Broadband 500MHz to 20GHz Digitally Controlled PIN Attenuator. This new product is part of AtlanTecRF’s range of ultra broadband microwave components and sub-systems designed for wide ranging applications in test and measurement, electronic countermeasures, scientific research and general communications.

This new Digital Attenuator (ADA-500-2000-60/0.5) covers the whole frequency range from 500MHz to 20GHz and provides a minimum attenuation range of 60dB in 0.5dB steps with TTL control of seven bits. Switching time is less than 200ns and the input power handling capability is up to 25dBm.

The miniature housing measuring just 45x30x12mm is of gold plated alloy with stainless steel SMA female RF input and output connectors with DC and TTL control connections being made via solder feedthru’s.

In making the announcement from the AtlanTecRF engineering base in Braintree, UK, AtlanTecRF CEO, Geoff Burling, said: “We continue to expand our product range with high performance and ultra broadband products and this new PIN attenuator with digital control brings to system designers, in so many different applications, product affordability and versatility in a single package."

The ADA-500-20000-60/0.5 operates from a ±5VDC supply with less than 70mA total current draw and exhibits a VSWR of better than 2.0:1 over an operating temperature range of -40 to 70°C.
