... This device is designed for operation in the saturated mode where it delivers a typical output power of +22 dBm (158 mW) with a power-added efficiency of 37%. The MGA-83563 has a large signal gain requiring an input signal level of only +4 dBm to drive it well into satu- ration. The high output power and high efficiency of the ...

... As previously noted, the internal input impedance match to the MGA-83563 is already reasonably good (return loss is typically 8 dB) and may be adequate for many ap- plications as is. The design of the MGA-83563 is such that the second stage will enter into compression before the first stage. The isolation provided by the first stage there- fore results in a minimal impact on the input matching as the amplifier becomes saturated ...

... Avago family of PHEMT GaAs RFICs. Linear Amplifier Thermal Example If the MGA-83563 is used in a linear application, the total power dissipation is significantly higher than for the saturated mode. The dissipated power is greater due to higher device current (not as efficient as the satu- rated mode) and also because no signal power is being removed ...

... P minimum I The optimum output match for 2.5 GHz was achieved with a shunt capacitor value of 0.9 pF located 0.08 inches along the 50 Ω line from the output pin of the MGA- 83563. The final output circuit is shown in Figure 24. RF Input ...

... B on the circle of the Smith chart. A series 2.5 nH inductor (L1) is then all that is required to complete the match to 50 Ω at Point C. While the input impedance of the MGA-83563 is some- what isolated from the nonlinear effects of the saturated output stage, some empirical optimization of the input inductor may increase the input return loss still further ...

... The input power was fixed at +4 dBm for this test. The length of the series line between the output of the MGA-83563 and C2 is also part of the matching circuit. This line was not considered as a variable in the sensitiv- ity analysis since photo-fabrication of micro-striplines on circuit boards is highly repeatable ...

... Note that the small signal input and output match provided by the internal matching of the MGA-83563 is sufficiently close to 50 ohms for most combinations of L2 and frequencies that further match- ing would not significantly skew the data. This is a small signal test and the input power level should be less than -15 dBm ...
