The datasheet says the power supply to HMC1082 is 5 V and absolute max. is 5.5 V.
Also it mentions that P1dB typical : 24 dBm which requires a 10 V swing (Vpk-pk)on a 50 ohm load.
The graph "P1dB vs. Supply Voltage" on page 2 also shows this value.
An explanation is appreciated if someone could tell how it can reach 24 dBm output power with a single 5 V supply
