The processing and control element (PCE) 105 is also used to power for the first filter mould group, and is instructed according to the test
In the working frequency range of trial signal to be measured determine the bandpass filter connected, and control the first filter mould group and connect the band
Bandpass filter；The first filter mould group, for from broadband signal receiving unit 101 receive signal after, using the band of connection
Bandpass filter is filtered the signal of input, and filtered signal is exported to first frequency selecting and filter unit 102.
As shown in figure 4, it is a kind of another structure of the power detection device for mobile communication in the embodiment of the present application
Schematic diagram.Wherein, first filter mould group 107 is when it is implemented, can pass through the realization pair such as single-pole three-throw switch or relay
The selection of bandpass filter.Preferably, the working frequency range of user setting detection device, processing and control element (PCE) 105 is then according to default
Working frequency range automatically control single-pole three-throw switch be switched on the filtering channel of corresponding frequency band.
In this way, 107 pairs of first filter mould group receive signals complete preliminary filter function, filter out outside working frequency range it is big do
Signal is disturbed, only there are three the signals of a certain frequency range in frequency range just can smoothly pass through first filter mould group 107.Then transfer to
One, the second frequency selecting and filter unit realizes the signal further progress frequency-selective filtering to selection test frequency range.It should be noted that appointing
The meaning moment, only there are three the bandpass filters of one of frequency range in band-pass filter of frequency band to work.
In order to adapt to the signal detection of full bandwidth, would generally shorten electronic device when signal frequency is higher uses the longevity
Life, in view of this, in the embodiment of the present application, the gain for the frequency range dynamic adjustment signal that can also be detected as needed.Specifically,
As shown in figure 4, the equipment further includes variable gain amplifying unit 108.Referring to Fig. 5, detection unit 104 includes 71 He of wave detector
Analog-digital converter 72；The detection unit 104 is also used to the electricity by analog-digital converter 72 to the detection tube output of wave detector 71
Pressure value carries out analog-to-digital conversion, and the voltage value being converted to is sent to the processing and control element (PCE) 105.The processing control is single
Member 105 is also used to power for the variable gain amplifying unit 108, and it is pre- to judge whether the voltage value of detection tube output is higher than
If voltage, if not, it is determined that the gain of variable gain amplifying unit 108 is not adjusted；If so, determining that variable gain is put
The gain of big unit 108；And according to determining gain, variable gain amplifying unit 108 is adjusted；The variable gain amplifying unit
108, the signal exported for receiving the first filter mould group 107, and by received signal according to processing and control element (PCE) 105
Determining gain is sent to first frequency selecting and filter unit 102 after handling signal.
In this way, feeding back to processing and control element (PCE) 105 when detection unit 104 detects voltage value and larger power, locate
Reason control unit 105, which then controls variable gain amplifying unit 108, reduces voltage value and power, to play protection equipment, extends
The effect of equipment life.
Referring to Fig. 5, variable gain amplifying unit 108 includes that the first digital step attenuator 31 for being sequentially connected in series, broadband are low
Noise signal amplifier 32, the second digital step attenuator 33, microwave amplifier 34.
The processing and control element (PCE) 105 determines signal power specifically for the voltage value exported according to detection tube, and according to
The linear relationship of signal power and gain determines the first pad value and second number of first digital step attenuator 31
Second pad value of word step attenuator 33；
Output is to institute after first digital step attenuator 31 decays according to signal of first pad value to input
State wideband low noise signal amplifier 32；The signal of 32 pairs of wideband low noise signal amplifier inputs exports after amplifying
To second digital step attenuator 33；Second digital step attenuator 33 is according to the second pad value to the letter of input
Output is to the microwave amplifier 34 after number being decayed；The signal of 34 pairs of microwave amplifier inputs exports after amplifying
To first frequency selecting and filter unit 102.
In this way, by digital step attenuator, wideband low noise amplifier and microwave amplifier, it can be by trial signal to be measured
Low noise amplification, detection dynamic range can also be extended to -110dBm-10dBm from 50dB~-10dB.
When it is implemented, the maximum gain of variable gain amplifying unit 108 can be 50dB, least gain can for-
10dB, gain adjustment amount then reach 60dB.Present invention take advantage of that the first digital step attenuator 31, wideband low noise signal amplify
Device 32, the second digital step attenuator 33 and microwave amplifier 34, detection unit 104 and processing and control element (PCE) 105 can make
The dynamic detection of equipment realization -110dBm-10dBm.
Specifically, when input signal is between -110dBm~-50dBm, the work always of variable gain amplifying unit 108
Make in maximum gain state, and the received voltage value of processing and control element (PCE) 105 is not above predeterminated voltage, processing and control element (PCE)
105 according to current voltage value, and the table by searching for voltage value and signal power corresponding relationship can calculate current input
Signal power.Maximum gain state, which refers to, is subject to processing control unit 105, the first digital step attenuator 31 and the second number
Step attenuator 33 is not at attenuation state i.e. signal and directly passes through, and wideband low noise amplifier 32 and microwave amplifier 34 are in
Magnifying state.
When input signal is between -49dBm-10dBm, the working condition of variable gain amplifying unit 108 is dynamic
Variation, i.e. gain is adjusted in dynamic.It is linearly increasing with input signal power, variable gain amplifying unit 108
Gain is linearly reduced.I.e. when the received voltage value of detection unit 104 is higher than predeterminated voltage, processing and control element (PCE) 105 is controlled
The pad value for making the first digital step attenuator 31 and the second digital step attenuator 33, makes variable gain amplifying unit 108
Gain linearity is reduced, to make the received voltage value of detection unit 104 lower than predeterminated voltage.Processing and control element (PCE) 105 simultaneously
