HMC1119

Thread Summary

The user inquires about the HMC1119's maximum allowable input level, comparing 24 dBm (RF Input Power) and 31 dBm (P1dB). The final answer clarifies that the maximum input power should not exceed 25 dBm, regardless of whether it is peak or continuous, to avoid damage. The user's condition of 19 dBm average and 31 dBm peak may lead to device damage or performance degradation.

As per the HMC1119 datasheet, the Input Linearity (P1dB) is specified as 31 dBm, while the RF Input Power (maximum recommended operating condition) is listed as 24 dBm.

In my lineup, the input signal level is 19 dBm average power, with a peak of 31 dBm.

Could you please clarify:

  1. Should the maximum allowable input level be taken as 24 dBm (RF Input Power) or 31 dBm (P1dB)?

  2. With my condition of 19 dBm average and 31 dBm peak, will the device operate reliably without damage or performance degradation?
