9. Analyze the Parameters
The parameters for the duplexer are determined.
Step 1. Determine the insertion loss and 3-dB bandwidth for Tx.
In the example shown in Figure 15-15, insertion loss (
loss) is 1.243 dB, and the 3-dB
bandwidth (
BW) is 85.53 MHz.
Step 2. Determine the insertion loss and 3-dB bandwidth for the Rx.
