Briefings

A 2026 white paper outlines how compact analog signal generators enable RF engineers to perform core amplifier and receiver tests, including gain and distortion measurements, blocker rejection, and local oscillator substitution. The document details methods for measuring gain compression at the P1dB point, evaluating two-tone intermodulation distortion via third-order intercept (IP3) comparison, and testing receiver performance under high-power interference conditions. It also explains the utility of signal generators for early-stage receiver development by replacing local oscillator and clock subsystems before final prototypes are built.

Key points

• Compact analog signal generators support core amplifier and receiver test tasks including gain and distortion measurements, blocker rejection, power calibration, and local oscillator substitution.
• Two-tone intermodulation distortion testing uses third-order intercept (IP3) to compare amplifier linearity, while receiver performance is tested under high output power and fast switching speed to simulate real-world interference.

Context and limitations

The evidence is limited to a 2026 white paper describing RF testing methods; specific manufacturer models, exact frequency ranges, or quantitative performance metrics are not provided.
