This amplifier can be used as is, or as a driver for higher-power devices. Figure 2-58B shows the construction details for transformer T1. Figures 2-58C and 2-58D show the component layout, and PC-board layout, respectively.Figures 2-58E, 2-58F, and 2-58G show typical amplifier performance characteristics. Those not familiar with microstrip techniques (for Z1, Z2, and Z3) should read the many Motorola publications, such as AN548A and AN555.
