8.1.1.2 Differential Input

Figure 8-2 shows how a simple network consisting of three resistors is used to match the differential input to a 100Ω differential source. Though the 1kΩ shunt resistor, RIN_SH, does not have any impact at dc to low frequencies, the resistor is necessary to get the full wideband performance from TRF1305x2. Figure 8-3 shows the configuration for ac-coupled differential input designs. The resistors values shown in Figure 8-2 and Figure 8-3 work for all gain versions of the TRF1305x2 for an 100Ω input match to a 100Ω differential source.

Use high-frequency (RF) resistors (0201 preferred), for high-frequency (RF) matching.
