HRF-AT4521

31.0 dB, DC - 2.5GHz, 5 Bit Serial Digital Attenuator

The Honeywell HRF-AT4521 is a 5-bit digital attenuator that is ideal for use in

broadband communication system applications that require accuracy, speed

and low power consumption. The HRF-AT4521 is manufactured with

Honeywell's patented Silicon On Insulator (SOI) CMOS manufacturing

technology, which provides the performance of GaAs with the economy and

integration capabilities of conventional CMOS. These attenuators are DC

coupled to improve lower operating frequency, frequency response and

reduce the number of DC bias points required.
