Max output power for RF Amp PHA-202+

[Tigera]

Hey,
I've got some POS-300 / POS -535 / POS-1025 VCO from Mini-Circuits with 10 dBm (or 8.5 dBm) power output. looking for a power amp and found PHA-202+
In datasheet mentioned "Medium power, 1W."
1W = 30 dBm = 20 Vpp into 50-ohm load

How it's possible to drive 20 Vpp while the DC supply voltage is only 11 V?
How much is the Max output power?

Thanks

Go back to basics and understand the relationships between current, voltage, resistance, and power.

Maximal output swing is > Vdc by using bias inductor

The relationships between current, voltage, resistance, and power are clear since load is 50 Ohm.
My question is how it's possible Vout > VDC ?

I think L1 and C2 are bias tee and C3 is decoupling capacitor for VDD.
Bias tees are designed to inject DC current into an RF circuit without affecting the RF signal through the main transmission path.
In RF frequency range L1 is open circuit so RF signal just pass through C2.
In DC L1 is short so pin 7 is also DC-IN for amp bias and C2 block DC , so at RF-OUT we just have RF signal and DC blocked.
