Hello,
We are using TRF370417 modulator. For this IQ signal is generated by DAC5670IGDJ. Between this I need to design a Bessel LPF with 550MHz -1dB bandwidth. This Filter must reject 1.2GHz DAC clock.
But DAC output pin impedance and Modulator Baseband input pin is different. So we are unable to finalise on the LPF topology. Could you please help us out.?
