Dear analog devices,
we are trying to use the device(HMC457qs16g power amplifier) slightly above the specified frequency.
At 2255MHz, we are not getting the P1dB of 30 to 31dBm.
It is drawing more current well below the P1dB mentioned in the datasheet.
Is it due to the limitation that device can work up to 2.2Ghz only or is there any other reason in biasing or output matching circuit?
We have used the schematic given in datasheet for 2100Mhz.
