Key Featrues
Wideband Coverage (50MHz to 4000MHz): This feature ensures the attenuator can operate across a broad frequency range, making it versatile for various applications such as wireless infrastructure, broadband systems, and general test equipment. Its wideband capability enhances its utility in diverse RF environments.
High Linearity (Greater Than +37.4dBm IIP3): The high linearity of the attenuator minimizes signal distortion, ensuring clean and accurate signal attenuation. This is particularly beneficial in high-performance systems where maintaining signal integrity is critical, such as in WCDMA/LTE and WiMAX base stations.
Dual Analog Attenuators with 23dB Range Each: The integration of two attenuators in a single device allows for cascaded attenuation up to 46dB, providing greater flexibility and control in signal management. This dual-channel design is ideal for complex RF systems requiring precise gain control.
SPI-Controlled 10-Bit DAC: The on-chip SPI-controlled DAC offers precise digital control over attenuation levels, simplifying integration into digital systems. This feature enhances ease of use and allows for automated control in applications like automatic level control (ALC) and temperature-compensation circuits.
Linear dB/V Analog Control Response: The linear control slope of 8dB/V simplifies automatic leveling control and gain-trim algorithms, making it easier to implement in systems requiring dynamic attenuation adjustments. This linearity ensures predictable and consistent performance across various attenuation settings.
