... differential AC input impedance of the LT5506 is about 200 , thus a 1:4 (impedance ratio) RF transformer with central tap can be used. In Figure 6, the evaluation board schematic is shown using a 1:4 transformer. The mea- sured input sensitivity of this board is about –82.6dBm for a 10dB signal-to-noise ratio. In the case matching circuit, the circuit of Figure 1 can be used ...
