Voltage-controlled microwave oscillator with micro-stripline filter |
摘要 |
A voltage-controlled microwave oscillator having a field effect transistor (1) as an amplifier and having a varactor diode (2) as a frequency-determining element has high output power and a large enough frequency sweep in the microwave frequency range that S-parameter scatters of the active components have optimally little influence on the characteristic data of the oscillator. The varactor diode (2) is preceded by a tunable micro stripline filter (3) and the source electrode of the field effect transistor (1) is directly connected to ground in order to form a parallel feedback with the micro stripline filter (3).
