Definition of "Balanced Amplifier" |
An amplifier with two identical branches connected to operate in opposite phase, with their input and outputs connections balanced to ground. A Push-Pull Amplifier. An amplifier having one output is considered balanced when the quiescent DC output voltage is reduced to zero or a specified level. An amplifier having two outputs is considered balanced when the difference between the quiescent DC output voltages is reduced to zero or a specified level. / Balanced Amplifier is the one in which there are two identical signal-handling branches operating in phase opposition, with input and output connections balanced to ground. / Practical capacitor and inductor as used in electric circuits are not ideal components with only capacitance or inductance. However they can be treated, to a very good degree of approximation, as being ideal capacitors and inductors in series with a resistance; this resistance is defined as the equivalent series resistance. If not otherwise specified, the ESR is always an AC resistance measured with standardized frequencies. / an amplifier in which two single-ended amplifiers are operated in parallel with 90 degree hybrid. Balanced amplifiers feature a low voltage standing wave ratio because of an absorption of reflected power at the terminating resistor of the hybrids. |
