HMC611LP4E Input power range

Hello Yuya,

1) There is no min/max limit, but datasheet graphs show typical 2dB log-linearity accuracy up to +10dBm. This is for frequencies of 50MHz to 7 GHz. The log-linearity graphs are based on an assumption of individual calibration of slope and intercept at room temperature, for that particular test frequency. Notice the Abs. Max. RF input power spec, +15dBm. 

2) Sorry I don't see that information readily available at this moment. But please consider, these devices are subject to variation due to the semiconductor mass production process. As a rough estimate, consider 0.2 to 0.3 Volts part-to-part variation is easily possible over a fairly large population of parts. 

For best accuracy, we recommend that the top level design incorporate provision for individual calibration, which means a provision to store slope and intercept coefficients in system non-volatile memory.   -Bruce H.
