HRF-AT4610
31.5 dB, DC - 4GHz, 6 Bit Parallel Digital Attenuator
The Honeywell HRF-AT4610 is a 6-bit digital attenuator ideal for use in broadband
communication system applications that require accuracy, speed and low power
consumption. The HRF-AT4610 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.
