lease just for clarification.
Third order intercept describes the power level at which the third order harmonic gain would intercept that of the desired gain?
IIP3 describes how much power seen or received by the LNA at which this point intercepts? And OIP3 is what exactly? dBm out of the...
by far and away
"handbook for microstrip antennas" 2 vol edition by james and hall is the best reference
this book handles everything from basics of single patch design to advance techniques of broadbanding arrays, beamforming and so forth
i find this 2 book set invaluable and recommend to...
follow your plan as above except with the 7th speaker place an appropriate load in shunt generating 4 ohm impedance
place 2 groups in series to achieve 8 ohms impedance
place the 8 ohm groups in shunt to achieve the 4 ohm impedance
connect to amp
of course you'll dump some power into the...
