HRF-AT4610

The Honeywell HRF-AT4610 is a 6-bit digital attenuator ideal for broadband communication system applications requiring accuracy, speed, and low power consumption. Manufactured using Honeywell's Silicon On Insulator (SOI) CMOS technology, it provides the performance of GaAs with the integration capabilities of CMOS.

This attenuator features a DC-coupled, bi-directional RF path, improving lower operating frequency response and reducing the need for multiple DC bias points. It offers attenuation in steps from 0.5 dB to 31.5 dB, with a typical insertion loss of 2.9 dB at 1.0 GHz and 5.8 dB at 4.0 GHz. The 1dB compression point is 24 dBm at 2.0 GHz (VSS=0V), and the typical input IP3 is 38 dBm at 2.0 GHz (VSS=0V).

Designed for ease of integration, the HRF-AT4610 utilizes a parallel data interface and operates from a single positive power supply voltage. It comes in a space-saving VQFN surface mount package, making it suitable for compact designs. The device is lead-free, RoHS compliant, and halogen-free.

Key electrical specifications include a typical operating voltage of 5.0V, a typical supply current of 50 uA, and a typical return loss of -13 dB. Switching speeds are also notable, with rise/fall times of 10 nS and turn-on/off times of 15 nS. The operating temperature range is -40 C to +85 C.
