Abstract
The utility model discloses a linear coaxial load, which comprises a connector, a RF cable, a RF cable fixation cavity and a load slice, wherein the connector is fixed on the outer wall of the RF cable fixation cavity, the RF cable is annually mounted in the RF cable fixation cavity, and connected with the connector, the load slice is fixed in the RF cable fixation cavity and connected with the RF cable. The signal is attenuated to facilitate the feature of the RF cable and the RF signal is not distorted, the bearing power of the load slice becomes smaller, and the load slice is not distorted in the linear region.
Description
Technical field
The utility model belongs to the network optimization product in electronic information and the mobile communication technology field, specifically a kind of linear coaxial load.
Background technology
Along with the communication technology two high speed development during the last ten years, the wiring of the existing a plurality of operators of the communication indoor distributed system of the high buildings and large mansions in existing city, for example: the GSM network of mobile operator and DCS network, the cdma network of operator of UNICOM, the PHS network of telecom operators also has the present 3G network of building etc.; Along with the carrier frequency of signal is more and more, more and more higher to the distortion factor requirement of signal accordingly, and there is the serious problem of distortion in existing coaxial load under this background.
The utility model content
The utility model provides a kind of linear coaxial load, has solved the serious problem of existing coaxial load linear distortion.
A kind of linear coaxial load described in the utility model, comprise joint, RF cable, RF cable fixed cavity and carrier sheet, described joint is fixed on the RF cable fixed cavity outside wall surface, the RF cable annular is installed in the RF cable fixed cavity, and RF cable is connected with joint, and carrier sheet is fixed in the RF cable fixed cavity and with RF cable and is connected.
Outside the RF cable fixed cavity, be provided with radiator.
Described carrier sheet is the load of single lead-in wire high frequency, and its lead-in wire by self is connected with the RF cable inner core.
The beneficial effects of the utility model are: the characteristic that is beneficial to RF cable is decayed by signal and not to the radio frequency distorted signals, the power that bears of carrier sheet diminishes, and makes carrier sheet undistorted in the range of linearity.
Description of drawings
Fig. 1 is the structural representation of the utility model cavity
Embodiment
As shown in Figure 1, a kind of linear coaxial load comprises joint 1, RF cable 2, and RF cable fixed cavity 5, radiator 3, carrier sheet 4, wherein:
Embodiment: it is 15 meters that certain linear coaxial load is provided with RF cable 2, the loss of cable is 0.4/dB rice during by 7630-0141 model 900MHz frequency, the i.e. loss of 15 meters RF cables is 6.0/dB, the intermodulation of existing carrier sheet model GSS-RIGS-1 is 43 dBm * 2 o'clock by existing measured power, for≤-110dBc, input signal power decays to 37 dBm * 2 after adding one section coaxial cable, power reduction 6 dBm, and the linearity improves 18dBc.Summarize the linearity that linear coaxial load can improve coaxial load, reduce the distortion factor of system.
