I am using ADL5243 for amplification. Now I need to amplify the signal which frequency is 1.2GHz, how can I choose Amplifier 2 matching components values? The datasheet don't have the correlate frequency matching components values
Unfortunately, we don't provide optimized component values for all frequencies, but Table 8 (Page 25) in the datasheet gives a good starting point for nine distinct frequencies. Any other frequencies not mentioned there should use the closest value - so 943 MHz in this particular case. That already should give a good starting performance, although some fine tuning may be needed.
