The Honeywell HRF-AT4521-GR-TR is a 5-bit serial digital attenuator designed for high-accuracy, high-speed, and low-power broadband communication systems. Utilizing Honeywell's proprietary Silicon-On-Insulator (SOI) CMOS technology, it offers performance comparable to GaAs devices with the economy and integration of CMOS.
This attenuator features a wide frequency range from DC to 2.5 GHz and provides a maximum attenuation of 31.0 dB. It operates with a single positive supply voltage and includes a serial data interface. The device boasts low DC power consumption and a 50 Ohm impedance. Its DC-coupled, bidirectional RF path improves performance at lower operating frequencies and reduces the need for DC bias points.
The HRF-AT4521-GR-TR is housed in a space-saving VQFN surface-mount package, making it suitable for compact designs. It is RoHS compliant and lead-free. The attenuator operates over a temperature range of -40°C to +85°C.

The positive supply VDD ranges from 3.31 V minimum to 5.5 V maximum (typical 5.0 V). A negative supply VSS of -5.0 V nominal is also required.
The device is supplied in a VQFN surface mount package.
The operating temperature range is -40 °C to +85 °C.
It operates from DC to 2.5 GHz.
The maximum attenuation is 31.0 dB, controlled by 5 bits (serial digital interface).
Typical insertion loss is 2.2 dB at 1.0 GHz.
At 2.0 GHz, the minimum input 1 dB compression point is 22 dBm with VSS=0 V and 28 dBm with VSS=-3 V.
