Absolute maximum input level overview - Absolute maximum input level without attenuation: +10 dBm - Absolute maximum input power with 30 dB attenuation: +20 dBm for a short time - Input interface point of third order modulation products (IIP3) with 0 dB attenuation: +15 dBm - 1 dB compression point at +2 dBm with 0 dB attenuation Why this matters - Clear protection for your downstream stages: defined input limits help prevent damage and maintain system reliability during testing and operation. - Predictable linearity for strong conversion tasks: IIP3 and compression points give you a reliable picture of how the signal will behave through the conversion path. - Flexible handling of high level signals: a 30 dB attenuation option allows short duration exposure to higher input powers without immediate risk to the core path. - Simple, robust performance metrics: compact set of well-defined specifications makes it easier to plan, test, and verify RF front-end behavior. Key benefits and what you get - Robust input handling: precise absolute maximums tell you how much signal you can apply without attacking system integrity. - Linearity and intermodulation visibility: IIP3 specification at 0 dB attenuation (+15 dBm) provides a clear indicator of third-order distortion performance. - Compression awareness: 1 dB compression point at +2 dBm (0 dB attenuation) defines headroom before nonlinear compression occurs. - Attenuation option for protection during testing: 30 dB attenuation allows higher input power to be applied briefly (+20 dBm) without exceeding critical limits. How it fits in a system - Function: RF input interface with defined power handling and linearity points tailored for strong conversion applications. - Compatibility: designed to integrate into RF signal chains that require known input thresholds, IIP3 guidance, and predictable compression behavior. - Performance focus: selects and preserves essential nonlinear and saturation characteristics to support accurate testing, calibration, and evaluation of conversion stages. Practical use scenarios - Scenario 1: Lab testing of a high-level RF front end - Use the 30 dB attenuation path to tolerate short surges up to +20 dBm during bench tests. - Monitor IIP3 at 0 dB attenuation (+15 dBm) to assess third-order distortion as you adjust input power. - Reference the 1 dB compression point (+2 dBm) to set safe operating margins for linearity measurements. - Scenario 2: Intermodulation and linearity characterization - Apply dual-tone or multi-tone signals within the IIP3 and compression ranges to quantify intermodulation products and compression onset. - Use the absolute maximums as safety thresholds to avoid damage during high-level excitation. - Scenario 3: Production or field measurement with transient events - Rely on the 30 dB attenuation option for short-duration high-power transients, ensuring protection of sensitive stages while still enabling meaningful test data. - Use the specified IIP3 and compression points to verify consistent performance across units or operating environments. Notes on usage - Respect the absolute maximum input levels to prevent damage to the device and connected components. - Use the 30 dB attenuation path when you anticipate brief high-power signals that exceed the 0 dB attenuation limits. - Refer to the IIP3 and 1 dB compression specifications to design test procedures and signal conditions that reveal the desired linearity and saturation behavior.
