Hi ,
in Ku band block up converter, The input frequency is 950 MHz to 1950 MHz . My question is the first harmonics of 950 MHz is 950*2= 1900 MHz. Which is in band of the system frequency . For Up converting if i fed the signal to the amplifier then the 1st harmonics will exists, i cannot filter out the first harmonics because it is in band of the system . Then for up covering i fed the signal to the mixer, output of the will contain the signal products such as L+IF , l+2*IF , the both signals are also in band of the system . Still there is a lot of SSPA modules are available in the frequency ? Can somebody explain how to remove all these spuries in this system??
