Description

Technical Field

[0001] The utility model relates to the technical field of combiners, in particular to a combiner with a built-in antenna. Background Art

[0002] A combiner is a device used in wireless mobile phone communication systems to combine input signals from multiple frequency bands and output them to the same indoor distribution system. In engineering applications, it is necessary to output 800MHz C network, 900MHz G network or other different frequencies simultaneously. Using a combiner, an indoor distribution system can operate simultaneously in CDMA frequency band, GSM frequency band or other frequency bands. For example, in a radio antenna system, the input and output signals of several different frequency bands (such as 145MHZ and 435MHZ) are combined through a combiner and connected to the radio station with a feeder. This not only saves a feeder, but also avoids the trouble of switching different antennas, and combines the reception and transmission of the signal mobile phone onto a single antenna. In the GSM system, since transmission and reception are not in the same time slot, the mobile phone can omit the duplexer used to isolate transmission and reception, and only needs to use a simple transceiver combiner to combine the transmission and reception signals onto one antenna without interfering with each other. For the receiving circuit, the antenna receives the signal, enters the receiving channel through the combiner, and mixes it with the receiving local oscillator signal (that is, the receiving VCO signal generated by the frequency synthesizer) to convert the high-frequency signal into an intermediate-frequency signal, and then performs orthogonal demodulation on the signal to generate receiving I and Q signals; then GMSK (Gaussian filtered minimum shift keying) demodulation is performed to convert the analog signal into a digital signal, which is then sent to the baseband processing unit for the transmitting circuit.

[0003] Application number CN202320939540.0 discloses a combiner with a built-in antenna, comprising a base, an input terminal, an output terminal, a mounting cavity, an antenna mechanism, and a locking mechanism. The utility model defines a mounting cavity at the top of the base. By disposing the antenna mechanism within the mounting cavity and unlocking the locking mechanism, a sliding block moves leftward under the action of a first spring, causing the mounting plate to rotate and unfold, thereby extending the antenna's transmission range.

[0004] Although the above-mentioned utility model has an installation cavity on the top of the base, and an antenna mechanism is arranged in the installation cavity, and the fixing of the locking mechanism is unlocked, the sliding block moves to the left under the action of the elastic force of the first spring, so that the mounting plate is rotated and unfolded, and the antenna is pulled out to expand the transmission range of the antenna, there is a disadvantage that when the device is in use, there are certain difficulties in installing and disassembling its shell, which may cause damage to the shell during subsequent disassembly and repair, resulting in a waste of resources.
