Abstract
A multiple-series amplifying device (100) of the present invention includes multiple series of amplifiers (110, 120) which are formed in parallel so as to input and output signals individually. Each of multiple-series of amplifiers (110, 120) includes a plurality of semiconductor amplifying elements (111, 112, 121, 122) which are driven in parallel so as to amplify signals. A pair of semiconductor amplifying elements (112, 121) adjoining together in a pair of amplifiers (110, 120) is formed in a single package (130).
Claims9
A multiple-series amplifying device comprising:
- a first amplifier including a first pair of semiconductor amplifying elements coupled together, wherein the first amplifier is configured to amplify a first high-frequency signal;
- and
- a second amplifier including a second pair of semiconductor amplifying elements coupled together, wherein the second amplifier is configured to amplify a second high-frequency signal,
- wherein the first amplifier and the second amplifier are disposed in parallel such that a first semiconductor amplifying element, included in the first pair of semiconductor amplifying elements, is positioned adjacent to a second semiconductor amplifying element included in the second pair of semiconductor amplifying elements, and
- wherein the first semiconductor amplifying element and the second semiconductor amplifying element are partitioned using an electric isolation and formed in a single package.
