HYBRID CIRCUIT CONSTRUCTION OF PUSH-PULL POWER AMPLIFIER

摘要

A means of connecting a plurality of essentially identical active devices (Q1,Q2, Q3, Q4) is presented for the purpose of multifunction and multiplefunction operation. These devices (Q1, Q2, Q3, Q4), mounted on a chip (66),are flip-mounted to a circuit motherboard having large passive elements. Apush-pull amplifier (50) is presented as an example in which the multiplefunction operation is the combining of amplifiers (56, 58) whose activedevices (Q1, Q2, Q3, Q4) are on a single chip (66). The electromagneticcoupling, impedance matching and signal transmission are variously provided bythe use of striplines (82, 88), slotlines (94, 100), coplanar waveguides (116,130), and a slotline (180) converted into a coplanar waveguide (176, 178).
