Repeat the analysis of the balanced amplifier of Example 12.7 using a 3 dB coupled line hybrid coupler. Use CAD software to optimize the input and output matching networks of the amplifiers to obtain a flat 10 dB gain response from 3 to 5 GHz, and compare the results with those obtained using the quadrature hybrid.

Example 12.7

Use the amplifier of Example 12.4 in a balanced configuration operating from 3 to 5 GHz. Use quadrature hybrids, and plot the gain and return loss over this frequency range. Using microwave CAD software, optimize the amplifier matching networks to give 10 dB gain over this band.
