Looking for P1dB data down to 30MHz input frequency. Does such data exist? Any guestimates?
The HMC321LP4 has a typical Input P1dB of +18dBm at 30MHz. The P1dB can be improved by ~1.5dB to +19.5dBm with slight forward biasing on the internal FETs; this application solution can easily be applied by adding an external shunt resistor of 33K-ohm at the RFC port. This solution will have no or minimal performance degradation on other parameters.
