The attached transmit circuit has very high S11 (and VSWR) at frequencies below 100 MHz. Adjust the values of the L,C shown in the shematic so that it has low VSWR (less than 1.3) and low S11 for the frequencies 60,70,80 MHz. The needed parameters are: 1. The output impedance at TX1_1 must be 50 ohms. 2. Transmit analogue input impedance 40 ohms 3. Transmit load impedance at the output pins 400 o...
