Wideband 6-Bit Digital Control, 0-31.5dB Range: This module utilizes the HMC472 IC, functioning as a wideband 6-bit digitally controlled attenuator. It offers an attenuation range from 0 to 31.5 dB with a precise 0.5 dB step size, featuring a typical step error of only ±0.25 dB. Designed for applications requiring accurate signal level management across a broad frequency spectrum from 1 MHz to 3.8 GHz
High Linearity with Low Insertion Loss: While providing a wide attenuation range, the module maintains excellent linearity, boasting a typical Input Third-Order Intercept (IIP3) of +54 dBm to help minimize intermodulation distortion with strong signals. Its typical insertion loss is below 2.0 dB, aiming to preserve system gain and noise figure performance
Single +5V Supply & Flexible Control Interface: Operating on a single +5V power supply (maximum +7V), it simplifies power design integration. Attenuation is controlled via an onboard 6-position DIP switch or pin header interface, supporting both manual adjustment and digital programming by an external controller for versatile operation
50Ω Impedance & SMA Connectors: The module features standard 50-ohm input and output impedance for good impedance matching with most RF test equipment, amplifiers, and filters. Signal ports use SMA female connectors, allowing for reliable connections with standard SMA cables for easy integration into your setup
Versatile for RF/IF Applications: Thanks to its wide bandwidth, precise attenuation, and good linearity, this module is suitable for various RF and IF applications in wireless communications, test and measurement, satellite systems, and military electronics. Common uses include Automatic Gain Control (AGC) loops, signal generator output level adjustment, and receiver front-end protection circuits
