Description
Technical field
The utility model relates to microwave-radio technology fields, are that a kind of complementary broadband coaxial is high-power negative specifically
It carries.
Background technique
Coaxial load is mainly used for absorbing the power of radio frequency or microwave system, and fictitious load and the transmitter that can be used as antenna are whole
End, can also be used as multiport microwave device, such as the matching port of circulator, directional coupler, to guarantee characteristic impedance
It is matched, carries out precise measurement.High-power coaxial load is divided into two kinds from internal structure, and one kind is that patch type loads (i.e.
With attenuator+patch load or the load of patch load production), one kind is that absorption load (makes of absorbing material negative
It carries).Both load advantage and disadvantage are obvious: surface mounting high-power loads frequency can be since DC, as frequency increases, and power is anxious
Play decline, the coaxial load of mean power 300w on the market, is hard to reach 10GHz frequency, voltage standing wave ratio also compares at present
It is poor.The power performance in high-frequency of absorption high power load is very excellent, and the absorption high power load of 18GHz can at present
To reach mean power 500w, but low-limit frequency is difficult to accomplish 2GHz or less.Absorption load is wanted to accomplish DC, the length of load
It will infinitely lengthen, it is unrealistic.This just brings many puzzlements to user, in order to test the power of a multiport device, needs
The high-power coaxial load of two kinds of different sizes is configured, sectionalization test is particularly troublesome.
As shown in Figure 1, being the internal structure of surface mounting high-power coaxial load.Connector 1, attenuator (are declined by conductor 2
Subtracting piece can not have, and can also be connected by multi-disc) 5, patch load 6 link together, attenuator 5 and patch load 6 are fixed on
On heat-dissipating casing 4.Microwave signal is transferred to attenuator 5 by connector 1, conductor 2, and energy is after the decrease of attenuator 5, transmission
It to patch load 6, is finally all absorbed by patch load 6, the heat of attenuator 5 and patch load all passes to heat-dissipating casing
4.Surface mounting high-power coaxial load for long wave (low frequency) absorb energy effect it is relatively good, energy absorption can since DC,
As frequency increases, power sharply declines.The coaxial load of current mean power 300w on the market, is extremely difficult to 10GHz.
As shown in Fig. 2, being the internal structure of absorption high-power coaxial load.Connector 1 connects conductor 2, and conductor 2 passes through
It is connected to after absorbing material 3 on heat-dissipating casing 4.Energy is radiated by conductor 2 by connector 1 and gives suction wave material by microwave signal
Material 3, then heat-dissipating casing 4 is passed to by absorbing material 3.Absorption high power load absorbs energy effect ratio for shortwave (high frequency)
Preferably, it is even higher to can achieve 18GHz for energy absorption, and power performance is also pretty good, can achieve mean power 500w with
On.But absorption load, by volumetric constraint, excessively poor for longwave absorption energy effect, low frequency is difficult to accomplish 2GHz.
There are no the high-power broadband coaxial loads that one kind can solve from DC to 18GHz (even higher frequency) at this stage.
