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.
