What does the working status of switch of Zhuo Shengwei radio frequency have?
The cent of working status core of switch of Zhuo Shengwei radio frequency isGuide (On State) AndClose (Off State) Mode of two kinds of foundations, all application setting all is based on the switch of these two kinds of condition and combination, specific definition and characteristic are as follows:
1.On-state (On State)
- Core function: Radio frequency signal but small loss ground is transmitted from the input port of switch to appoint output port, be equivalent to circuit ” access ” .
- Crucial function asks: Need to assure mainly below this conditionLow insert loss(reduce signal attenuation) andTall segregation is spent(avoid signal to string together faze to arrive other did not guide a port) , ensure efficient, stability transmits signal.
- Typical setting: When 5G mobile phone need is received / emissive some is specific frequency paragraph (the N41 frequency that is like Sub-6GHz paragraph) when signal, corresponding frequency paragraph meeting switch reachs radio frequency switch on-state, let signal enter the follow-up filter, module such as amplifier through switch.
2.Close position (Off State)
- Core function: Block breaks radio frequency signal to be transmitted between the input of switch and output port, be equivalent to circuit ” open circuit ” .
- Crucial function asks: Need to assure mainly below this conditionTall segregation is spent(utmost prevents cross talk) andHigh-end mouth impedance(the signal that reduces pair of other route is disturbed) , avoid useless signal to enter working circuit.
- Typical setting: Come when switch of 5G mobile phone other frequency paragraph (like N78 frequency paragraph) when the job, former N41 frequency paragraph meeting switch reachs corresponding radio frequency switch close position, prevent N41 frequency paragraph stray signal disturbs current job frequency paragraph signal processing.
Compensatory: The condition of multiterminal mouth switch is combined
Switch of Zhuo Shengwei radio frequency withShort-hilted broadsword casts more (SPxT, be like SP4T, SP8T) The type is given priority to (satisfy much frequency paragraph communication demand) , essence of its job status is ” only port guides + the others port closes ” combination:
- For example, a SP4T (short-hilted broadsword 4 cast) radio frequency switch, same time can have 1 only ” knife – cast ” access is in on-state, additionally 3 access all are in close position, implement number of different frequency Duan Xin through this kind of switch choose, much frequency of comfortable mobile phone matching 5G paragraph, the communication demand of much mode.
