IMPATT pipes provide DC bias signal, and disclosure satisfy that the special clamping requirement of IMPATT pipes.
Technical solution
The present invention devises a kind of feed circuit with unique displacement function.By the cylinder and the bottom that select various outer diameter
Disk realizes that cylinder is used for feeding, and chassis is used for fixed purpose；It is real by the spring characteristic different in different torque bottom offsets
The different displacements of existing feeder pillar；By the introducing of felt pad, feeder pillar and outer wall short circuit are prevented；It is formed by introducing bimetallic ring
" chokes ring " prevents interfering with each other for high-frequency signal and DC bias signal.By the design of the above link, realization is based on
The feed and commissioning requirements of the 3mm microwave devices of IMPATT pipes.
A kind of feed circuit based on IMPATT pipes, it is characterised in that including upper feeder pillar, spring, lower feeder pillar, insulation
Pad, becket and cavity；Upper feeder pillar and lower feeder pillar are made of cylinder and disk, and the disk of upper feeder pillar is fixed on cavity
A port on, the chassis of lower feeder pillar is located in the another port of cavity, between two chassis be equipped with spring, lower feed
The cylinder of column is pierced by cavity, is equipped with felt pad and becket successively on the cylinder of lower feeder pillar.
The chassis of the upper feeder pillar is more than the chassis of lower feeder pillar.
The becket is two.
Upper feeder pillar, lower feeder pillar, cavity and the becket is all made of HPb59-1Y copper.
The felt pad uses polytetrafluoroethylene (PTFE) SFB-1.
It is Φ 0.2mm, number of total coils 8.5, pitch of the laps that the spring, which uses 60SiMnA steel wires, screw pitch 0.5mm, thickness,

Specific implementation mode
In conjunction with embodiment, attached drawing, the invention will be further described：
The overall structure of this feed circuit based on IMPATT pipes illustrate as shown in Figure 1, entire circuit by upper feeder pillar,
Spring, lower feeder pillar, felt pad, becket, cavity composition.Upper and lower feeder pillar is made of cylinder and chassis respectively, column body with
External signal realizes that the feed-in of signal, lower prop are in direct contact with IMPATT pipes, biasing is provided for pipe by the form of welding
Signal, upper and lower feeder pillar chassis is opposite to be placed in cavity, and spring is added between upper and lower feeder pillar chassis, makes lower feeder pillar
Corresponding displacement can be generated according to torque size.On the one hand this design enables external dc offset signal be fed directly into electricity
On the other hand road can meet the special commissioning requirements that the later stage needs IMPATT pipes to be capable of upper and lower displacement.It is upper and lower to present in design
Electric column and cavity are all made of HPb59-1Y copper as material, and the chassis outer diameter of lower feeder pillar is smaller compared with the internal diameter of cavity, this be for
Reduce friction, and by calculating required torque size, material of the final choice 60SiMnA steel wires as spring, spiral shell repeatedly
Away from for 0.5mm, thickness is Φ 0.2mm, number of total coils 8.5, a diameter of Φ 1.6mm of pitch of the laps.Overall structure size is shown in Table 1,2.
In the lower end of feed circuit, it is placed in felt pad, bimetallic ring successively, felt pad uses polytetrafluoroethylene (PTFE) SFB-1, gold
Belong to ring and uses HPb59-1Y copper.In design, the internal diameter of felt pad is suitable with the lower outer diameter of feeder pillar cylinder, on the one hand ensures
On the other hand the concentricity of feeder pillar prevents feeder pillar from contacting with outer chamber wall generation short circuit.Meanwhile felt pad bottom is double
Becket forms accurate coaxial filter structure with feeder pillar, which can generate inhibition to high-frequency signal, prevent high-frequency signal logical
