Key benefits and purpose - Enables direct evaluation of RF signals up to practical levels without attenuation, helping you assess device linearity and distortion in real-world conditions. - Provides a safe path for brief high power tests by using a 30 dB attenuator to reach +20 dBm at the input for short durations, expanding test options without compromising protection. - Delivers a clear IIP3 reference point at the input, assisting in predicting third-order intermodulation behavior during two-tone and multi-tone tests. - Defines the compression threshold with 0 dB attenuation, enabling precise determination of the onset of nonlinearity and usable dynamic range. Core specifications - Absolute maximum input level without attenuation: +10 dBm This marks the continuous, distortion-free upper limit of the input signal when no attenuation is used. - Absolute maximum input power with 30 dB attenuation for a short time: +20 dBm Allows brief exposure to higher signal power with attenuation in the input path to protect the device during transient tests. - IIP3 (input interface point of third order intermodulation products) with 0 dB attenuation: +15 dBm Indicates the input level at which third-order intermodulation products become significant, useful for planning linearity experiments and predicting in-system behavior. - 1 dB compression point (P1dB) with 0 dB attenuation: +2 dBm Specifies the onset of noticeable compression, defining the practical linear operating region for measurements and test setups. Function and performance highlights - Direct input path performance is characterized by an IIP3 of +15 dBm at 0 dB attenuation, enabling standard two-tone and multi-tone linearity analysis. - The device tolerates a continuous input up to +10 dBm without attenuation, supporting typical measurement scenarios without extra loss. - For short duration high-power testing, applying 30 dB attenuation permits up to +20 dBm at the input, broadening test coverage while maintaining protection. - The P1dB point at +2 dBm (0 dB attenuation) provides a concrete reference for the onset of nonlinear behavior, supporting accurate dynamic range assessment. Compatibility and integration notes - Suitable for RF measurement setups that require direct IIP3 and P1dB references, as well as controlled high-power testing with attenuation. - Designed to work within standard RF signal chains where attenuation can be applied at the input to manage power levels during tests. - The specifications define the safe operating envelope and nonlinear thresholds necessary for planning experiments and validating DUT performance. Use scenarios - Lab linearity characterization: Use the IIP3 and P1dB references to map the device under test’s linear range and predict third-order distortion under two-tone conditions. - Two-tone and multi-tone distortion testing: With IIP3 at 0 dB attenuation, perform precise intermodulation measurements to evaluate how the DUT responds to closely spaced carriers. - Short-duration high-power testing: When brief high-power stimuli are needed, apply a 30 dB attenuator to achieve up to +20 dBm at the input for a short period, protecting the device while probing peak behavior. Applications - RF component development and validation - Laboratory characterization of amplifiers and front-end blocks - Measurement setups requiring defined IIP3 and P1dB references for accurate nonlinear modeling
