RECEIVER RF PORT IMPEDANCE MATCH MEASUREMENT DATA

Receiver RF Port Impedance Match Measurement Data for 30 MHz to 3 GHz Band Match
Return loss was measured on RX1(2)A and RX1(2)B RF ports of eval boards and plotted below; blue and pink curves represent four
different return loss measurements and black dotted line represents simulated return loss curve on Figure 175 and Figure 176. Simulated
insertion loss curve including balun loss is plotted on Figure 177.
