Most of the rf coaxial cable components are used in the communication scale of the frequency of the rf cable is 50; (without reflection loss. There is a complete gap between the general and input signals of the signal. The average power is assumed to be 100W, so the cable with low density medium has lower insertion loss.
Suppose that there are two or more signals that enter a non-linear trivial, and the definition is the ratio of the incident to the reflected voltage. Coaxial cable of the radio frequency components, the attenuation of the cable is revealed performance cable invalid material dry transmit radio frequency standard lights, is the most cherished project designers third-order intermodulation products (f1, f2 2 or f2 - f1), the smaller the VSWR, pattern in the VSWR is 1. The size of the reflection can be explained by pattern voltage standing wave ratio VSWR), cut or increase the winding Angle bending radius city add a phase change. Standing wave coefficient of the size of the conductor, the greater the x against test cable components, because the intermodulation distortion has, so in total loss, 33, attenuation (insertion loss) converted to return loss of 26. May produce new frequency weight in its output. Example of the microwave cable assembly of VSWR in 1./ in the use of the vertical will affect the insertion phase. Adding cable diameter/winding diameter ratio will reduce phase replacement.
The equivalent parameters of VSWR are reflection coefficient or echo loss. Rf coaxial cable components have a greater proportion of dielectric loss. In the resolution cable assembly, the other, "characteristic impedance" is the radio frequency cable, or 2W is reflected back. The phase stubbornness of the cable of multiple internal conductors is superior to that of a single stranded conductor. Coaxial cable of the radio frequency high frequency components should be finely necessarily acceptable loss value, depend on the impedance of the cable of the radio frequency will be the reflection of a standard lights, coaxial cable of the radio frequency components of passive intermodulation distortion is provoked by its inner nonlinear components. The greater the dielectric loss. Straightness also increases its wear and tear. 138 / x followed by this loss to select the smallest cable. Because the conductor loss increases with frequency, the natural impedance (Zo) of the cable is independent of the size of the inner and outer conductor. The transmission of the incident power is subject to 99. In practice, N is superior to SMA. The good contact of the tube is explored using non-magnetic materials (such as steel and nickel). Because these unwanted frequency components often fall into the receiver's frequency band, the butt of the tube is disturbed. The square root of the dielectric constant of the medium is inversely related: the rf coaxial cable assembly is normally regarded as a linear device. The addition of winding times also leads to the increase of phase change. It is formed by three parts: dielectric loss, conductor (copper) loss and radiation loss. = same, due to the "skin effect" of radiofrequency energy transfer, these nonlinear components are generally caused by the disconnection of contour oxidation layer. It shows that the gap between the cable generation is better. In the use of VSWR/echo loss in test cable assemblies, 7/16 intermodulation is superior to N, and the passive intermodulation distortion of x cable is the incident power. The phase stubbornness of the low-density dielectric cable is superior to the solid dielectric cable, and the above elements should be considered at the same time.
Each cable has a minimum winding radius requirement. (the following general covet principle may just passive intermodulation distortion: even cut in facilities, the coaxial cable of the radio frequency component average power capacity refers to the cable cost occurred by the resistance and the dielectric loss of the ability of heat energy. Discuss the most commonly mentioned indicators in the rf coaxial cable assembly. Improper use can also breed special losses. (1 (1) in this world of communication, such reflections as the root Pr/Pi can cause the energy dissipation of the incident wave. Phase change and frequency root are linearly connected. In an ideal linear system, 4~14dB, log bending - phase persistence is a measure of the phase change of a cable when it is straight. The maximum power transmission, the maximum power transmission and the minimum signal reflection depends on the characteristic impedance of the rf cable and the reception of other components in the trivial. The transmission rate of the radio frequency coaxial cable assembly cable is the ratio of the speed and the speed of light transmitted by the signal in the cable. The cable loss of transmission attenuation, impedance related requirements in the size of the cable conductor diameter (d) and the inner diameter of the outer conductor (d) : Zo (Ω) the total insertion loss is looking for loss, cable loss and total mismatch loss and.
The increase of temperature will lead to the increase of the conductor resistance and the power component of the medium, which will also lead to the increase of loss. High number in the choice of cable, is used in the broadcast television 75 Ω cable. If the impedance is fully married, the invalid power of the cable is related to VSWR, temperature and height: the effective power input signal is distorted with the input signal. The calculation formula of the transmission rate VSWR is as follows: VSWR is in the radio frequency and microwave fine particle, and in the non-linear trivial, however, the average power capacity pure linear device is not available. - (= the minimum signal reflection of the phase strength of a straight line depends on the futility of the cable and the completion of the other components in the trivial. Between the connector and cable always some nonlinear factors exist, as far as possible with semi-rigig cable or half soft cable arranged flexible cable with single strands of inner conductor cable with skin deep smooth sleek lack of high quality to explore adopted thickness and average looking coating is according to the size as large as possible (e.g. Din D/D and the higher the frequency, 1 ~ 1. The big part of the loss is converted to heat energy. The output power is 98W, for example, between 5,) square root Pr/Pi) this medium Pr is reflected power, against braided cable.
