3 CIRCUIT DESCRIPTIONS MITEQ's AMF Series SATCOM amplifiers capitalize on technology developed at MITEQ during the past 25 years. This technology had been mainly in support of the radiometry community providing state-of-the-art low noise amplifier designs. Based upon a hybrid Microwave-Integrated-Circuit (MIC) approach, MITEQ utilizes chip-and-wire-construction to minimize losses to the input stage as well as supporting the subtle adjustments needed to achieve the optimum match for VSWR and noise figure. MITEQ s SATCOM amplifiers are offered with and without the use of input isolators. In both cases, feedback is the technique used in the input stage to facilitate impedance matching for an optimum balance of power (VSWR) and noise figure. SHUNT FEEDBACK SERIES FEEDBACK FEEDBACK AMPLIFIER STAGE detailed knowledge of the transistor and impedance matching circuits to achieve the best performance. MITEQ is not the only company using feedback approach to achieve low noise figures; however, many of our competitors must utilize input and interstage isolators to allow them to provide good VSWR performance in the presence of the best noise match. Although isolators are sometimes used for special applications, MITEQ has proven an ability to achieve both a good power match and an optimum noise match without isolators. This gives us a great advantage over our competition by providing the lowest noise figures available. FEEDBACK AMPLIFIER NOISE TEMPERATURE VERSUS NOISE FIGURE FEEDBACK DESIGNS Feedback based designs use a single transistor in each stage. The impedance of the FET is matched to the input or output source and load impedance by means of coupling a portion of the output signal back into the input with frequency dependent elements. Two basic types of feedback are applied, series or parallel. Series feedback is also known as "lossless" feedback because there is no additional lossy circuits added to the input of the FET. Although difficult to optimize, a lossless feedback design provides the lowest noise figures available today. In implementing this design, the engineer must pay particular attention when impedance matching the input stages. The interaction of power and noise match of the transistor must be optimized over the specified band. This optimization of a feedback amplifier design involves a tradeoff exercise between input VSWR and noise figure performance. The matching techniques utilized are best accomplished in "chip and wire" construction where subtle tuning can be realized. It is an area that requires extensive experience and a NOISE TEMPERATURE (Kelvin) NOISE FIGURE (db) NOISE TEMPERATURE (Kelvin) NOISE FIGURE (db)
