I need to create a 10 MHz square wave clock signal which gets terminated into a 50 ohm resistor for use by a waveform generator. The specifications for the waveform generator suggest a 12 to 14 dBm power level for the input clock. ie. a power level of ~16-25mW.
So I've been looking to buy an oscillator circuit component online of which there are plenty but I can't find anything at all which meets those power specifications. The way I'm calculating the power is by:
[tex] p_{rms} = \dfrac{v_{rms}^2}{R} [/tex]
[tex] v_{rms} = V_H \sqrt{D}[/tex]
Which means i need a high level of [tex] V_H = 1.12V [/tex]
Is the power output calculated in this way for RF specifications of this sort or am I doing something wrong? Or are Oscillator ICs just generally not available with these power levels? If so what are my options? I'm a physics student currently doing a bunch of electronics stuff so I'm still not incredibly familiar with a lot of specifications given on data sheets but I'm definitely willing to do some reading.
