This amplifier can be used as is or two amplifiers can be combined with quadrature-couplers to form a 100-W amplifier. Figure 2-59B shows the construction details for transformers T1/T2, Figures 2-59C and 2-59D show the component layout, and PC-board layout, respectively. Figures 2-59E, 2-59F, and 2-59G show typical amplifier performance characteristics. Those not familiar with microstrip techniques （for Z1 through Z5） should read the many Motorola publications,such as AN548A and AN555．
