Specific embodiment
The preferred embodiment of the present invention is introduced below with reference to Figure of description, keeps its technology contents more clear and convenient for reason Solution.The present invention can be emerged from by many various forms of embodiments, and protection scope of the present invention is not limited only to text In the embodiment mentioned.In the accompanying drawings, the identical component of structure indicates that structure or function is similar everywhere with same numbers label Component is indicated with like numeral label.
As shown in Figure 1, a kind of power amplifier with harmonic suppression circuit, mainly includes rf inputs 1, input matching Network 2, bonding line 3, biasing circuit 4, series resonant network 5, series resonant network 6, load matching network 7, Choke inductance 8, Loaded antenna 9, input transistors 10 and cascode transistor 11.One end of input matching network 2 connects rf inputs 1, and The other end connects the grid of input transistors 10, and the source level of input transistors 10 is connected to ground reference by bonding line 3, defeated Enter matching network 2 and bonding line 3 and realize the input resistant matching of power amplifier jointly, and guarantees the stabilization of power amplifier Property.Biasing circuit 4 is connected with the grid of input transistors 10 and cascode transistor 11 respectively, is 10 He of input transistors Cascode transistor 11 provides bias voltage.5 one end of series resonant network is connected with the drain terminal of cascode transistor 11, separately One end connects ground reference, is shorted to ground for harmonic signal.The leakage of series resonant network 6 one end and cascode transistor 11 End is connected, and the other end is connected with load matching network 7, for inhibiting the transmission of harmonic signal.7 one end of load matching network It is connect with series resonant network, the other end is connected with loaded antenna 9, for 50 Ω of antenna to be impedance-matched to power amplification The optimum load of device energy Maximum Power Output.
As shown in Fig. 2, input matching network 2 is by capacitance C1With on-chip inductor L1Composition, the source level of input transistors 10 It is connected with bonding line 3, a positive real impedance can be generated in input terminal, then the imaginary part resonance of input terminal exists by inductance L1 Working frequency, so that input impedance is meshed well into.The routing radical of bonding line 3, length of wire bonding will affect defeated Enter the stability of impedance value and power amplifier, therefore by the routing radical and routing of bonding line 3 in case study on implementation of the invention Length is set as adjustable, to meet requirement of the actual chips to impedance matching and stability, i.e., pre- when designing circuit layout The case where routing is determined when a certain number of pads (Pad) having been stayed to can be used for subsequent actual test.
Biasing circuit 4 is that input transistors 10 and cascode transistor 11 provide DC voltage bias, mainly inclined by generating Set voltage VB1And VB2Voltage-reference (be not drawn into figure, replace V with voltage sourceB1And VB2) and two RC low-pass filters Composition.Wherein unillustrated voltage-reference needs work under wide power voltage in figure, and provide Low Drift Temperature coefficient, and stablize Reliable bias voltage VB1、VB2.Two RC functions of low-pass filter are identical, for biasing circuit 4 and power amplifier to be isolated Amplifier tube, influence of the big signal of the influence of noise and power amplifier that avoid biasing circuit to biasing circuit.Resistance and electricity The value of appearance is generally bigger, but it is also contemplated that big influence of the Resistance Thermal Noise to power amplifier, wherein R1And C3Composition RC low-pass filter is used for cascode transistor 11, and R2And C2The RC low-pass filter of composition is used for input transistors 10.
Input transistors 10 and cascode transistor 11 provide signal amplification, due in RF application to transistor Requirement it is relatively high, be generally adopted by radio-frequency performance preferably depth N hydrazine RF transistors, while the noise isolation of depth N hydrazine pipe It is also very good to spend.Input transistors 10 can achieve higher speed using the lesser RF tube of line width in the present embodiment, There is better radio-frequency performance, obviously advantage is had to the processing of signal;Cascode transistor 11 using thick grid with And the RF transistors of long line width.What is generally handled due to power amplifier is big signal, in the drain terminal of cascode transistor 11 Instantaneous voltage can reach twice of supply voltage, be likely to breakdown RF transistors at this time, can be big using thick gate transistor The earth increases its breakdown pressure voltage, so that the RF transistors of power amplifier are more safe and reliable, while cascode crystal The speed of pipe influences power amplifier will not be very big.Therefore, the combination of such transistor types can achieve extraordinary effect Fruit.
Series resonant network 5 has two groups of capacitor and inductors to be composed in series, and for filtering out secondary and harmonic signal, improves line Property degree.Since the concatenated resonant network of inductance capacitance is that low-resistance even may be considered short circuit at resonance frequency.Practical application In, the bonding line 3 of pad to the encapsulation of chip interior can be equivalent to the relatively high inductance of Q value, after being connected in series to the capacitor i.e. Constitute series resonance chamber.Wherein, C4And B2Constitute the suppression circuit of second harmonic signal, and C5And B3It constitutes humorous three times The suppression circuit of wave signal.Since the length of bonding line and the deviation of technique may be such that resonance frequency generates deviation, because This bonding line B2And B3Routing can be set flexibly, similar with bonding line 3, length of wire bonding is that can adjust with routing radical Section, need to reserve a certain number of pads in design chips domain, while concatenated capacitor can do some adjustment and trim. Since secondary and harmonic signal influences maximum to the output signal of power amplifier, only joined in the present embodiment Second order and three order harmonics suppression circuits similarly, can quadravalence in parallel and higher orders in the application example of other requirements at the higher level Harmonic suppression circuit is to achieve the purpose that inhibit higher hamonic wave signal.
Series resonant network 6 is by inductance L2With capacitor C6Form a parallel resonance chamber.Theoretically parallel resonance chamber is in resonance The impedance of frequency be it is very big, can be similar to open a way, then since the inductance Q value of actual use is limited, resonance frequency Impedance is also limited.Wherein inductance L2For on-chip inductor, Q value is not high but inductance value can be more accurate than bonding line, resonance frequency The bandwidth that rate can compare at accurate resonance frequency simultaneously also can be bigger, and impedance is less than normal, but can satisfy and press down to harmonic signal The requirement of system.Influence due to harmonic signal to fundamental frequency signal is maximum, or even since non-linear harmonic signal can hinder The output of fundamental frequency signal is filled in, therefore the resonance frequency of the series resonant network 6 in this example is set as harmonic signal and corresponds to Frequency, further suppress the output of harmonic signal.Since the Q value of resonant cavity is lower, the suppression circuit is to second harmonic Signal is also to have certain inhibiting effect.It similarly, can be by cascading more parallel resonances in the transmitter of requirements at the higher level Network, and corresponding resonance frequency is set as the corresponding frequency of higher hamonic wave signal and can inhibit more higher hamonic wave signals pair The influence of fundamental frequency signal.
Load matching network 7 is by capacitance C7With the inductance L for being parallel to ground3Composition.Bulky capacitor C7It is mainly used for being isolated The effect of direct current signal, because the drain terminal voltage of cascode transistor 11 is substantially supply voltage, rear class has the direct current of oneself Bias voltage considers that the connection of late-class circuit needs for two direct current biasings to be isolated.And in the power amplifier in this example Best match load be capacitive load, as long as according to SMITH circle diagram analysis it is found that an inductance can be by 50 Ω of antenna Load matched to the position of optimum load, due to the inductance value to inductance require it is relatively high, Q value is required it is but less high, therefore The present embodiment still uses on-chip inductor L3To realize load matching network.Similarly, the optimum load of different embodiments may It can have differences, matching network would also vary from, but can't change the structure of power amplifier proposed by the present invention.
As shown in figure 3, the impedance of series resonant network is imitative when working frequency corresponding in the present embodiment is 2.45GHz It can clearly be seen that two concave points, corresponding impedance is almost nil in true figure, it can be approximately considered and be shorted to ground, and it is corresponding Frequency is respectively 4.9GHz and 7.35GHz, the i.e. place of the two of working frequency times and treble frequency.This one small impedance can incite somebody to action The harmonic signal of respective frequencies is shorted to ground, to reduce influence of the harmonic signal to output fundamental frequency signal, while in 2.45GHz Position on impedance or bigger, the harmonic suppression circuit is smaller to the loss of fundamental frequency signal.
As shown in figure 4, corresponding working frequency is 2.45GHz in this example, the resonance frequency of series resonant network 6 should It is arranged at treble frequency, i.e. 7.35GHz.Such as figure, there is resonance point in the position of 7.35GHz, corresponding impedance is very big, So big impedance makes harmonic signal that can not be transferred to output end to be curbed well.Fundamental frequency signal simultaneously Position impedance it is substantially zeroed, therefore the series resonant network can be very good inhibit higher hamonic wave without will affect fundamental frequency letter Number transmission.
Fig. 5 is when harmonics restraint/be added without harmonic suppression circuit is added, and the output power of power amplifier is with input power Emulation change curve.Measuring the most common index of power amplifier linearity performance is 1dB compression point, therefore Fig. 5 is corresponding Be exactly power amplifier 1dB compression point simulation curve figure.As shown, this Example power is put when harmonic suppression circuit is added The output 1dB compression point of big device can achieve+21.7dBm, and this Example power amplifier when being added without harmonic suppression circuit Exporting 1dB compression point is only+17.3dBm, this can not meet requirement for many applications, therefore the present invention proposes Harmonic suppression circuit have extraordinary harmonic suppression effect to the power amplifier of the present embodiment, it will be apparent that improve power and put The linearity performance of big device, while also improving the peak power output and emission effciency of power amplifier.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that the ordinary skill of this field is without wound The property made labour, which according to the present invention can conceive, makes many modifications and variations.Therefore, all technician in the art Pass through the available technology of logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea Scheme, all should be within the scope of protection determined by the claims.
