HI all,
I am currently doing a DDS function generator which will generate 20 Vpp sine wave within 0-40 MHz.As frequency higher,the amplitude from DDS module become lower which are when frequency is 1MHz, amplitude= 1.25V and when f=40Mhz,amplitude=250mV which are quite low, that why I need to design a amplifier which can maintain the amplitude of the signal in 20Vpp for all frequency (0-40MHz)
The first solution come in my mind is to use https://www.ti.com/product/tl026 this product, but I am not sure it will work or not,so any suggestion on how to design the circuit??
Thanks
