Hi,
I have two RF power amplifiers.
The first one works in frequency range 60-75 GHz and the second works in 75-90 GHz.
Is it possible to combine the two PAs to realise a PA working in the frequency range 60-90 GHz?
If it is possible, how?
I considered,
1, Parallel connecting the two PAs. The phase information of the PA output is unavailable.
2, Serial connecting the two PAs. The first output power would exceed the input power of the second PA. An attenuator to limit the input power to the second PA?
Any suggestions are welcome.
Thanks
