The Honeywell Solid State Electronics Center (SSEC), in conjunction with worldwide distributor Richardson Electronics introduced the HRF-AT4000 family of high performance attenuators. Manufactured using Honeywell's Silicon On Insulator CMOS technology, they offer both serial and parallel interface architectures. In addition to architecture latitude, the HRF-AT4000 series 5- and 6-bit attenuators are available in 4 mm × 4 mm (16-pin LPCC surface mounted) packages to enable applications requiring high accuracy, speed and extremely low power consumption such as cellular basestations and handset products.
The Honeywell SOI CMOS based attenuators operate on a single positive supply voltage and have high isolation resistance. Additional SOI benefits include a unique combination of integrated CMOS control logic and ESD protection, and a frequency range of DC to 4 GHz.
