Compared with prior art, using such as Fig. 2 and Fig. 3 four mould radio architectures, can greatly save power amplifier quantity and
The making space of pcb board.Specifically, single-frequency power amplifier only can carry out power amplification processing to the signal of a frequency range, if
It is required that supporting 3 kinds of frequency ranges, then need to set 3 single-frequency PA, in this case, total number of lines needs to be multiplied by 3, this increase
The cabling difficulty and manufacturing cost of pcb board, and use multifrequency power amplifier (for example, power amplifier) of the present utility model, when requiring support 3
During kind of frequency range, this multifrequency PA can save the cabling space of 2 VBAT, 2 VCC, 5 VMODE and 2 VEN lines, one
In individual embodiment, the circuit design of pcb board is the size according to supply current, and VBAT lines need 0.5-1mm line widths, and VCC line is needed
1mm line widths are wanted, VMODE lines and VEN lines respectively need 0.1mm line widths.Therefore, PCB cabling can be greatlyd save using multifrequency PA
Space, the space saved can such as increase filtering part to eliminate other letters for optimizing the surrounding enviroment of other signal wires
The noise components of number line.
Further, in the prior art, multifrequency power amplifier is used only for supporting this 4 frequencies of WCDMA BAND 1258
Section, but the multifrequency PA in the utility model can also then support WCDMA BAND 3,13,20 and 26.Due to BAND 3 frequency
Section is in 1710M-1785M, and this frequency range is in outside BAND2 frequency ranges 1850M-1910M bandwidth, and if desired multifrequency power amplifier is supported
BAND2 and BAND3, it is necessary to can have band stray between considering successive bands and the signal such as bottom is made an uproar, influence multifrequency power amplifier
Performance.Therefore, multifrequency power amplifier of the present utility model uses broadband amplifiers NZ5634, and it has higher out-of-band power linear
Degree, and the framework of the impedance circuit using L+ π types, disclosure satisfy that BAND3 frequency range demand.Similarly, BAND13,20,26
Realized using above-mentioned multifrequency power amplifier, specific frequency is then determined by rear end matching and debugging.
In a comparative example, it is assumed that mobile phone needs to use this 7 frequency ranges of BAND1,3,5,8,13,20,41, if according to existing
There is technology, there can be two schemes：One is to support BAND1,3,41,4 4G low-frequency power amplifiers point respectively using 3 4G radio frequency power amplifiers
Not Zhi Chi BAND5,8,13,20,7 power amplifiers are needed altogether；Two be to support BAND41,2 4G low frequency work(using 1 4G radio frequency power amplifier
Put support BAND13,20,1 multifrequency power amplifier and support remaining BAND1,3,5,8,4 power amplifiers and one group of matching multifrequency are needed altogether
The switch of power amplifier.According to framework of the present utility model, then 1 4G radio frequency power amplifier is only needed to use to support BAND 41, it is remaining
BAND1,3,5,8,13,20 can directly be supported by 4G multifrequency power amplifiers NZ5634, and can obtain preferable signal effect.
Specifically, the manufacturing cost contrast of the utility model and prior art, it is found advantageous that：1st, save
PA quantity, if for example, make 2 frequency ranges, such as support telecommunications LTE BAND1 and EVDO BAND5, then using Fig. 1 framework only
Two single-frequency PA are set, as this design cost with prior art, it is necessary to about 2 single-frequency PA price (USD0.15 ×
2), further, if making N (N>2) individual frequency range, the design of prior art is to use N number of single-frequency PA, and cost is USD0.15
× N, but framework cost of the present utility model is the price of mono- group of single pole multiple throw of USD0.3+, such as N=4 is existing to set
Meter needs USD0.15 × 4=USD0.6, and framework of the present utility model only needs to USD0.3+0.05 × 2=USD0.4, wherein
USD0.05 is the unit price of single-pole double-throw switch (SPDT), used here as two switches.On the whole, the band number of required support is more,
More PA quantity and cost can be saved using the utility model.2nd, printed circuit board (PCB) (PCB) wiring space is saved, due to
The utility model employs multifrequency PA, can save the quantity of part circuit, therefore effectively reduces PCB manufacture area, you can
To save part PCB cost.
