The values for this network were determined using optimization with the =SuperStar= computer program. The results are shown in Figure 1-7. The flatness is within a few tenths of a decibel. 69843 Slls222ooo - 7 . 66834 C. 11 Figure 1-6 Auantek AT60585 transistor responses with 1 pF shunt capacitance at the input. 98799 Figure 1-7 Avantek AT60585 transistor with matching at the input and output. essary when computer simulation techniques are utilized. The schematic of the completed design is given in Figure 1-8.

This feedback path is an opportunity for oscillation to occur. The reflection coefficients presented to the transistor by the matching networks affect the stability of the amplifier. A stability factor, K, is Analysis Fundamentals 17 TI 3 AT605> T 1PF T __L - 75” -I- - Figure 1-8 Bipolar 2 - 4 GHz transistor amplifier with matching at the input and output optimized to flatten the gain. 42 where When K>l, C11<1, and C22c1, the two-port is unconditionally stable. That means that the two-port is stable for all input and output loads with positive real components.

In this case, the parallel capacitance is important at higher frequencies. For lower resistance values and high frequencies, the reactance of the lead inductance is more significant. Figure 1-13 shows the schematic of a simple 108 to 300 MHz amplifier similar to the amplifier in Figure 1-9, but using a 2N5179 transistor and feedback resistors with parasitics. The results are shown in Figure 1-14. The solid traces in each case are with ideal resistors with no parasitics. On the upper left (LRF), the dashed response is with 9 nH of inductance added to the resistor Q.
