Description
Technical Field
The invention belongs to the technical field of frequency sources, and particularly relates to a duplex phase-shifting dielectric oscillation type frequency source with fundamental second harmonic double-frequency point impedance matching.
Background
With the development of communication technology, radar and satellite communication technologies are widely applied and technically innovated in the civil and military fields, and the communication system has higher and higher requirements on frequency sources, namely the frequency of an output signal is improved, and the requirements on indexes such as signal phase noise are improved. In order to meet the demand, researchers have designed push-push type dielectric oscillators based on direct oscillation type dielectric oscillators.
Two fundamental wave oscillation signals generated by a medium oscillation module in the push-push type oscillator have a phase difference of 180 degrees, and after the two fundamental wave oscillation signals are output under the action of a nonlinear device, multiple harmonic signals can be generated in two output signals, wherein corresponding even harmonic waves in the two output signals are in the same direction, and corresponding odd harmonic waves in the two output signals are in the opposite direction. Then the odd harmonics are offset after the combination, and the even harmonics with enhanced power are output. The push-push type dielectric oscillator utilizes a push-push type structure to reduce phase noise on one hand, and utilizes second harmonic combined output to improve output frequency and power on the other hand.
The phase noise level of the output signal can be improved only by ensuring that the phases of the second harmonics in the two paths of signals are the same during the combination, and the generation of stray signals is reduced, so that the two paths are required to be completely the same, and the generated phase shifts are the same. However, due to differences of devices, microstrip circuits and the like caused by various factors, the phases of two paths of signals are different, and the differences become a main factor for limiting the phase noise performance of the oscillator; moreover, the output impedance of the negative resistance transistor in the dielectric 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 application of the oscillator are limited; in addition, the phase difference of the two fundamental wave signals is 180 degrees, and the two fundamental wave signals are offset after being combined, so that the energy waste of the fundamental wave signals is also caused.

Therefore, signals containing fundamental waves and second harmonics are obtained at the input end of the duplexer, and the corresponding fundamental waves are reverse and the second harmonics are in phase. After the signal passes through the duplexer, a fundamental wave signal and a second harmonic signal are separated, the fundamental wave signal is output to a matched load, and the second harmonic signal is input to a phase shifter to be combined after phase adjustment. The phase of the two paths of signals is in phase only when the two paths of signals are combined, so that the stray output signals and the excellent phase noise performance can be ensured, but the two paths of circuits have differences, so that the phases of the two paths of signals are different when the two paths of signals are combined, and the phases of the two paths of signals are adjusted by adjusting the phase shifter.

Detailed Description
The technical scheme of the invention is explained in detail by combining the drawings and the embodiment. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Examples
The embodiment is a duplex phase-shifting dielectric oscillation type frequency source with fundamental second harmonic double-frequency point impedance matching, and fig. 2 is a circuit schematic diagram of the embodiment. The transistor model of the first negative resistance transistor module 12 and the transistor model of the second negative resistance transistor module 13 are BFU 730F; 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 waves and second harmonics; the first duplexer 4 and the second duplexer 5 adopt a matched and connected structure of two Chebyshev band-pass filters, 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 type 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-shifting dielectric oscillation type frequency source for fundamental second harmonic double-frequency point impedance matching comprises the following specific working processes:
a first resonance signal V generated by the dielectric resonance module 11 1 (t) with a second resonance signal V 2 (t) are of equal amplitude, frequency and opposite 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 negative resistance transistor module 12 and the second negative resistance transistor module 13 are respectively inputted, a first oscillation signal V after oscillation amplification is obtained at the output ends of the first negative resistance transistor module 12 and the second negative resistance transistor module 13 OSC1 (t) second oscillation signal V OSC2 (t) of (d). Due to the non-linearity of the transistors, the oscillating signal contains multiple harmonic signals, taking into account the phase shift introduced 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) +…
Δ 121, Δ 122, Δ 123, Δ 124 … are the phase shifts introduced 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) +…
Δ 131, Δ 132, Δ 133, Δ 134 … are phase shifts caused by the second negative resistance transistor module 13. The existence of the first dual-frequency impedance matching module 2 and the second dual-frequency impedance matching module 3 not only ensures that the dielectric oscillation module 1 starts oscillation 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 that the oscillation signal V is OSC1 (t)、V OSC2 The fundamental wave signal and the second harmonic signal in (t) are 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 terminals of the first duplexer 4 and the second duplexer 5 due to circuit mismatch.
The input signal V is obtained at the input end of the first duplexer 4 by considering the phase shift brought by the impedance matching module with double frequency points 4 (t)：
V 4 (t)＝A 1 e j(ωt+Δ121+Δ21) +A 2 e j(2ωt+Δ122+Δ22)
Wherein Δ 21 and Δ 22 are phase shifts brought by the first dual-frequency impedance matching module 2.
Similarly, an input signal V is obtained at the input of the second duplexer 5 5 (t)：
V 5 (t)＝A 1 e j(ωt-π+Δ131+Δ31) +A 2 e j(2ωt+Δ132+Δ32)
Δ 31 and Δ 32 are phase shifts brought by the second dual-frequency impedance matching module 3.
After passing through the first duplexer 4 and the second duplexer 5, the signal is separated into fundamental wave and second harmonic wave signals, the fundamental wave signal is obtained at the low frequency output terminal of the first duplexer 4 and the second duplexer 5, and the second harmonic wave signal is obtained at the high frequency output terminal of the duplexers 4 and 5.
Taking into account the phase shift introduced by the duplexer, the signal V is obtained at the low-frequency output of the first duplexer 4 41 (t) obtaining a signal V at the high-frequency output of the first duplexer 4 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 Δ 41 and Δ 42 are phase shifts introduced by the first duplexer 4.
Similarly, a signal V is obtained at the low-frequency output of the second duplexer 5 51 (t) obtaining a signal V at the high frequency output of the second duplexer 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)
Here, Δ 51 and Δ 52 are phase shifts by the second duplexer 5.
Signal V 42 (t)、V 52 (t) after being input into the first phase shifter 6 and the second phase shifter 7, the signals V can be 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 Δ 6 is the phase shift brought by the first phase shifter 6, and is adjustable as needed.
V 7 (t)＝A 2 e j(2ωt+Δ132+Δ32+Δ52+Δ7)
Where Δ 7 is the phase shift introduced by the second phase shifter 7, and is adjustable as required.
Signal V output via phase shifter 6 (t)、V 7 And (t) is input into the combiner 8 for combining, and the combiner 8 also generates additional phase shift for the two signals. Thus signal V 6 (t)、V 7 (t) signal V obtained after input to 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)
Δ 81 and Δ 82 are phase shifts caused 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 completely the same, the final phase difference Δ is equal to 0, that is, the two signals are in the same direction, so that a second harmonic signal with excellent phase noise is obtained at the output end of the combiner 8.
However, due to the difference and imbalance of the devices, the phase difference Δ ≠ 0, which results in poor signal quality after combining. At this time, the phase shifters 6 and 7 are adjusted to adjust the phase difference Δ to 0, so that the signal V becomes a signal V 81 (t) sum signal V 82 (t) have the same phase, and the signals V output by the combiner 8 are 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 improved power is obtained.
The above-described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by a person skilled in the art without making any inventive step, with reference to the embodiments based on the present invention, fall within the scope of protection of the present invention.
Finally, it should be noted that the present invention is not limited to the above alternative embodiments, and that any person can obtain other products in various forms 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 by the appended claims.
