In figure 21, an example is shown of a signal split up to feed multiple low power amplifiers, then recombined to feed a single antenna with high power. [51] Figure 21. Splitter and combiner networks used with amplifiers to produce a high power 40 dB (voltage gain 100) solid state amplifier Figure 22. Phase arrangement on a hybrid power combiner.
A BJT phase splitter. A phase splitter is a device that separates a signal [clarification needed] into multiple phases (or polarities).. The term is most often applied to amplifiers that produce two "balanced" voltage outputs: of equal amplitude but opposite polarity (i.e. 180 degrees phase difference), but sometimes is used to refer to the generation of quadrature signals (i.e. differing by ...
RF switch matrix. An RF switch matrix is an array of RF switches arranged to route radio frequency (RF) signals between multiple inputs and multiple outputs. Applications requiring RF matrices include ground systems, test equipment, and communication systems. An RF matrix is used in test systems, in both design verification and manufacturing ...
Audio crossovers are a type of electronic filter circuitry that splits an audio signal into two or more frequency ranges, so that the signals can be sent to loudspeaker drivers that are designed to operate within different frequency ranges. The crossover filters can be either active or passive. [ 1] They are often described as two-way or three ...
Analog multiplier. In electronics, an analog multiplier is a device that takes two analog signals and produces an output which is their product. Such circuits can be used to implement related functions such as squares (apply same signal to both inputs), and square roots . An electronic analog multiplier can be called by several names, depending ...
Wilkinson power divider. In the field of microwave engineering and circuit design, the Wilkinson Power Divider is a specific class of power divider circuit that can achieve isolation between the output ports while maintaining a matched condition on all ports. The Wilkinson design can also be used as a power combiner because it is made up of ...
A valve amplifier or tube amplifier is a type of electronic amplifier that uses vacuum tubes to increase the amplitude or power of a signal. Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers in the 1960s and 1970s. Valve amplifiers can be used for applications such as ...
In electronics, a current divider is a simple linear circuit that produces an output current ( IX) that is a fraction of its input current ( IT ). Current division refers to the splitting of current between the branches of the divider. The currents in the various branches of such a circuit will always divide in such a way as to minimize the ...
