摘要： A balun and transformer system (201) is provided in which a balun (112) is cascaded between two 4:1 impedance transformers (102, 110) to form a 16:1 broadband impedance transformation for push-pull amplifier applications (200). The balun (112) is configured in a Marchand configuration. The balun and transformers (201) are formed with coupled lines realized with a very thin layer of ceramic. Additional coupling between the gap in the balun (112) is achieved by an embedded capacitor (260) built in the balun's ceramic. DC bias supply (294, 296) to the power amplifier (106) is achieved by using the hot plate of decoupling capacitors (298, 299), which serve as a floating ground plane to the whole application (200).

摘要： A constant “R” network distributed amplifier formed in a multi-layer, low temperature co fired ceramic structure comprises multiple cascaded constant “R” networks for amplifying a signal applied thereto. Each one of the multiple cascaded constant “R” networks is formed in the ceramic structure and includes a plurality of ceramic layers each of which have a top and bottom planar surfaces which, when bonded together form the ceramic structure. A transmission line is formed on the top surfaces of each of the ceramic layers having a beginning end and a distal end and has a generally rectangular shape. The distal end of the transmission line formed on a lower ceramic layer is connected to the beginning end of the transmission line formed on the next adjacent upper ceramic layer by way of vias formed in the ceramic layers through which metal conductive material is formed there through. The transmission lines and the capacitance established between the individual layers form a LC structure. An output is provided at the middle portion of the transmission line formed on the middle ceramic layer that is coupled to the drain of a FET.

摘要： A hybrid low voltage distributed power amplifier structure (300) provides improved efficiency by forming drain transmission line inductors (323) on a substrate (306) while the rest of the amplifier is built in IC form (302). A wirebond interconnection (330) is made between the IC's drainline capacitors (324) and the substrate's drainline inductors (323) which are a higher impedance point in the circuit. As a result, the wirebond inductance becomes negligible and has little or no impact on the power amplifier's performance.

摘要： A GaAs monolithic true logarithmic amplifier which includes at least one amplifier stage common to the two arms of the circuit, the two arms being independent thereafter, one having lower gain and higher compression point and the other arm having higher gain and lower compression point. The signals in the arms are then recombined off-chip to provide the same effect as in the prior art. The circuit includes an input stage which amplifies and gain shapes the input signal and then splits the signal into upper and lower paths. The upper path is a relatively lower gain and higher compression point path whereas the lower path is a relatively higher gain and lower compression point path. The upper path includes a FET with a very large gate width whereas the lower path includes plural cascaded FETs, the last of which has a very small gate width. The upper and lower paths both have an odd or an even number of FETs to maintain the phase relation therebetween, the upper path further including transmission line stubs or elements which act as a delay line to compensate for the delay in the lower path due to the larger number of FETs therein. The outputs of the upper and lower paths are combined in a resistive combiner to provide the amplified signal. The output of this circuit is linear at low power and then demonstrates a knee therein at higher input power to resemble the curve of a logarithmic amplifier.
