Description
Technical Field
The invention belongs to the technical field of frequency sources, and particularly relates to a duplex phase-shifting inference medium oscillation type frequency source with fundamental wave second harmonic double-frequency point impedance matching.
Background
With the development of communication technology, radar and satellite communication technology are widely applied and technically innovated in civil and military fields, and the requirements of a communication system on frequency sources are higher and higher, on one hand, the frequency of output signals is improved, and on the other hand, the index requirements of signal phase noise and the like are improved. To meet the needs, researchers have designed push-push dielectric oscillators based on direct-oscillating dielectric oscillators.
The phase difference of two road wave oscillation signals generated by a medium oscillation module in the push-push type oscillator is 180 degrees, and after the two road wave oscillation signals are output under the action of a nonlinear device, multiple harmonic signals can be generated in the two paths of output signals, wherein corresponding even harmonic waves in the two paths of signals are in the same direction and odd harmonic waves are in opposite directions. The odd harmonics after combining cancel and the even harmonics with enhanced output power. The push-push type medium oscillator utilizes a push-push type structure to reduce phase noise on one hand and utilizes second harmonic combining output to improve output frequency and power on the other hand.
Only if the second harmonic phases in the two paths of signals are the same during the combination, the phase noise level of the output signals can be improved, and the generation of stray signals is reduced, so that the two paths are required to be identical, and the generated phase shifts are identical. However, the difference exists between devices, microstrip circuits and the like due to various factors, so that the phase difference of two paths of signals is caused, and the phase difference becomes a main factor for limiting the phase noise performance of an oscillator; the output impedance of the negative resistance transistor in the medium oscillation module is not matched at the second harmonic, so that the output signal power of the second harmonic is low, and the performance and the application of the oscillator are limited; in addition, the two paths of signals are 180 degrees out of phase, and after the two paths of signals are combined, the two paths of signals are counteracted, so that the energy waste of the fundamental wave signals is caused.

Only when the phases of the two paths of signals are in phase during the combination, the excellent performances of spurious output signals and phase noise can be ensured, but the two paths of circuits have differences, so that the phases of the two paths of signals are different during the combination, and at the moment, the phases of the two paths of signals are adjusted by adjusting the phase shifter.

The technical scheme of the invention is described in detail below with reference to the accompanying drawings and examples. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Examples
An embodiment is a duplex phase-shifting propulsive dielectric oscillating type frequency source with fundamental wave second harmonic wave double frequency point impedance matching, and fig. 2 is a schematic circuit diagram of the embodiment. Wherein the transistor model in the first negative resistance transistor module 12 and the second negative resistance transistor module 13 is BFU730F; the first double-frequency point impedance matching module 2 and the second double-frequency point impedance matching module 3 adopt a parallel multi-branch matching structure, and can perform impedance matching at fundamental wave and second harmonic; the first duplexer 4 and the second duplexer 5 adopt two chebyshev band-pass filters to be matched and connected, and the pass band covers fundamental wave and second harmonic frequency points; the first phase shifter 6 and the second phase shifter 7 are reflection phase shifters based on branch line couplers, and the working frequency covers a second harmonic frequency point; the combiner 8 is a Wilkinson power divider, and the working frequency band covers the second harmonic frequency point.
The embodiment of the duplex phase shift inference medium oscillation type frequency source for fundamental wave second harmonic double-frequency point impedance matching comprises the following specific working processes:
the first resonance signal V generated by the dielectric resonance module 11 1 (t) and the second resonance signal V 2 (t) identical in amplitude, identical in frequency, opposite in phase, i.e. 180 ° out of phase:
V 1 (t)＝a 1 e jωt
V 2 (t)＝a 1 e j(ωt-π)
when the resonance signal V 1 (t)、V 2 (t) when the first and second negative resistance transistor modules 12 and 13 are respectively inputted thereto, the first oscillation signal V after oscillation amplification is obtained at the output ends of the first and second negative resistance transistor modules 12 and 13 OSC1 (t) second oscillation signal V OSC2 (t). Due to the non-linearities of the transistors, the oscillating signal contains multiple harmonic signals, taking into account the phase shift brought about by the transistors.
V OSC1 (t)＝A 1 e j(ωt+Δ121) +A 2 e j(2ωt+Δ122) +A 3 e j(3ωt+Δ123) +A 4 e j(4ωt+Δ124) +…
Where Δ121, Δ122, Δ123, Δ124 … are phase shifts brought about by the first negative resistance transistor module 12.
V OSC2 (t)＝A 1 e j(ωt-π+Δ131) +A 2 e j[2(ωt-π)+Δ132] +A 3 e j[3(ωt-π)+Δ133] +A 4 e j[4(ωt-π)+Δ134] +…
＝A 1 e j(ωt-π+Δ131) +A 2 e j(2ωt+Δ132) +A 3 e j(3ωt-π+Δ133) +A 4 e j(4ωt+Δ134) +…
Wherein Δ131, Δ132, Δ133, Δ134 and … are phase shifts caused by the second negative resistance transistor module 13. The existence of the first dual-frequency point impedance matching module 2 and the second dual-frequency point impedance matching module 3 not only ensures that the medium oscillation module 1 starts to vibrate smoothly at the fundamental frequency, but also respectively performs impedance matching on the output ends of the first negative resistance transistor module 12 and the second negative resistance transistor module 13 with the input ends of the first duplexer 4 and the second duplexer 5 at the fundamental frequency and the second harmonic frequency, thereby ensuring the oscillation signal V OSC1 (t)、V OSC2 The maximum power of the fundamental wave signal and the second harmonic wave signal in (t) is transmitted to the input terminals of the first duplexer 4 and the second duplexer 5. And other harmonic signals cannot be transmitted to the input ends of the first duplexer 4 and the second duplexer 5 due to circuit mismatch.
Taking into account the phase shift caused by the dual-frequency point impedance matching module, an input signal V is obtained at the input end of the first duplexer 4 4 (t)：
V 4 (t)＝A 1 e j(ωt+Δ121+Δ21) +A 2 e j(2ωt+Δ122+Δ22)
The Δ21 and Δ22 are phase shifts brought by the first dual-frequency point impedance matching module 2.
Likewise, an input signal V is obtained at the input of the second diplexer 5 5 (t)：
V 5 (t)＝A 1 e j(ωt-π+Δ131+Δ31) +A 2 e j(2ωt+Δ132+Δ32)
The Δ31 and Δ32 are phase shifts brought by the second dual-frequency point impedance matching module 3.
After the signals pass through the first duplexer 4 and the second duplexer 5, fundamental wave signals and second harmonic signals in the signals are separated, the fundamental wave signals are obtained at the low-frequency output ends of the first duplexer 4 and the second duplexer 5, and the second harmonic signals are obtained at the high-frequency output ends of the duplexers 4 and 5.
Taking into account the phase shift brought about by the diplexer, a signal V is obtained at the low frequency output of the first diplexer 4 41 (t), in the firstThe high frequency output of the diplexer 4 gets the signal V 42 (t):
V 41 (t)＝A 1 e j(ωt+Δ121+Δ21+Δ41)
V 42 (t)＝A 2 e j(2ωt+Δ122+Δ22+Δ42)
Where Δ41 and Δ42 are phase shifts caused by the first diplexer 4.
Likewise, a signal V is obtained at the low frequency output of the second diplexer 5 51 (t) obtaining the signal V at the high frequency output of the second diplexer 5 52 (t):
V 51 (t)＝A 1 e j(ωt-π+Δ131+Δ31+Δ51)
V 52 (t)＝A 2 e j(2ωt+Δ132+Δ32+Δ52)
Where Δ51 and Δ52 are phase shifts due to the second diplexer 5.
Signal V 42 (t)、V 52 (t) after being input to the first phase shifter 6 and the second phase shifter 7, respectively, a signal V is obtained at the output ends of the first phase shifter 6 and the second phase shifter 7 6 (t)、V 7 (t)：
V 6 (t)＝A 2 e j(2ωt+Δ122+Δ22+Δ42+Δ6)
Where Δ6 is the phase shift imparted by the first phase shifter 6, which is adjustable as desired.
V 7 (t)＝A 2 e j(2ωt+Δ132+Δ32+Δ52+Δ7)
Where Δ7 is the phase shift brought about by the second phase shifter 7, which is adjustable as required.
Signal V output through phase shifter 6 (t)、V 7 (t) is input to a combiner 8 for combining, and the combiner 8 also imparts an additional phase shift to the two signals. Thus signal V 6 (t)、V 7 (t) a signal V obtained after input to the combiner 8 8 (t)：
V 8 (t)＝A 2 e j(2ωt+Δ122+Δ22+Δ42+Δ6+Δ81) +A 2 e j(2ωt+Δ132+Δ32+Δ52+Δ7+Δ82)
Where Δ81, Δ82 are the phase shifts brought about by the combiner 8.
The final phase difference is therefore:
Δ＝(Δ122+Δ22+Δ42+Δ6+Δ81)-(Δ132+Δ32+Δ52+Δ7+Δ82)
if the two devices are identical, the final phase difference Δ=0, i.e. the two signals are in the same direction, so that a second harmonic signal with excellent phase noise is obtained at the output of the combiner 8.
However, the phase difference Δ+.0 is caused by the device differences and imbalance, resulting in poor signal quality after combining. At this time, the phase of the signal V is adjusted by adjusting the phase shifters 6 and 7 so that the phase difference Δ=0 81 (t) sum signal V 82 (t) the phases are the same, and the signal V outputted by the combiner 8 is combined out (t) is:
V out (t)＝2A 2 e j(2ωt)
finally, the second harmonic signal with ultralow phase noise, high harmonic suppression and high power is obtained.
The above-described embodiments are merely some, but not all embodiments of the invention. All other embodiments, which are obtained by a person skilled in the art without making any inventive effort, are considered to be within the scope of protection of the present invention.
Finally, it should be noted that the invention is not limited to the alternative embodiments described above, but can be used by anyone in various other forms of products in the light of the present invention. The above detailed description should not be taken as limiting the scope of the invention, which is defined in the following claims.
