The EXB-24AT1AR3X is a compact chip attenuator in a 1.0 mm x 1.0 mm package, designed for high-frequency signal attenuation and impedance matching. It features an integrated, unbalanced π-type circuit that provides a fixed attenuation of 1 dB with a tolerance of ±0.3 dB. This device operates over a broad frequency range from DC to 3.0 GHz with a characteristic impedance of 50 Ω and a maximum VSWR of 1.3. The power rating is 0.04 W at 70°C, and it operates reliably across a temperature range of -55°C to +125°C. Its single-chip construction reduces mounting area and cost, making it suitable for space-constrained applications like cellular phones, PDAs, and other communication equipment.
