Description

Technical Field

[0001] The utility model belongs to the technical field of wireless communications, and in particular relates to an ultra-wideband multi-channel transceiver system. Background Art

Under the premise of ensuring performance, the RF transceiver channel component takes into account the compatibility of installation in terms of structural design and unifies the structure; in terms of channel link design, regardless of the receiving channel or the transmitting channel, the positions of the power input terminal and the control signal input terminal of all active devices are kept consistent, so as to achieve interchangeability / replaceability between several transmitting channels and between several receiving channels. Preferably, the positions of the RF glass insulator pins for power supply and control signal lead-out of the component are exactly the same. Accordingly, the connection position between the control module and each RF channel component is designed to be compatible with the receiving channel and the transmitting channel. Preferably, the input and output ends of the RF receiving channel and the RF transmitting channel both use male SMP RF connectors.

[0024] Preferably, the RF receiving channel, RF transmitting channel, local oscillator module, and local oscillator power distribution network use micro-assembly technology to complete the interconnection assembly between the microwave transmission line and the microwave bare chip.

[0028] Preferably, if Figure 1 As shown, the RF transceiver channel component is a four-channel TR component, and both the RF receiving channel and the RF transmitting channel adopt a four-channel integrated design.

[0029] Preferably, the local oscillator module is used to generate the local oscillator signal required for the two-stage frequency conversion of the RF receiving channel and the RF transmitting channel. Figure 1 As shown, there are two types of local oscillator modules, two of each type, one generates a local oscillator signal with a variable frequency, and the other generates a local oscillator signal with a fixed frequency. The local oscillator modules are lightweight in design.

[0030] Preferably, the local oscillator power division network is connected to the local oscillator module and the RF transceiver channel component, and is used to distribute the RF local oscillator signal to the RF transceiver channel component. In order to realize the time-sharing operation of transceiver, the local oscillator power division network needs to be adjusted according to the arrangement order of the multi-channel transceiver channels.

[0031] Preferably, the local oscillator power division network has several single-pole double-throw switches built in, which follow the switching control changes of the receiving and transmitting states. When the channel is in the receiving state, the switch is selected to supply the local oscillator signal to the receiving channel; when the channel is in the transmitting state, the switch is selected to supply the local oscillator signal to the transmitting channel. The receiving and transmitting channels have independent local oscillators.

[0032] Preferably, the control module is used to power the RF receiving channel, the RF transmitting channel, the local oscillator module, and the local oscillator power division network and control their working states. It adopts vertical interconnection technology to connect with the RF receiving channel and the RF transmitting channel, expanding the vertical plane space. The control board has a unified design for the connection with the RF transceiver channel component for power supply and control, and can arbitrarily combine multiple transmitting channel modules, multiple receiving channel modules, or a combination of multiple transmitting channel modules and receiving channel modules, effectively solving the interchangeability of multi-channel transceiver modules and realizing the miniaturization of the product. Furthermore, the control module controls the working state of the transceiver channel, and realizes the time-sharing operation of the receiving and transmitting channels by controlling the enable end of the power supply LDO. When the transmitting channel is working, the power supply of the receiving channel is turned off; when the receiving channel is working, the power supply of the transmitting channel is turned off.

[0033] Preferably, if Figure 4 As shown, the control function of the control module is mainly implemented by FPGA. The module not only has a separate discrete port to control the switching of multi-channel receiving and transmitting states and the setting of attenuation values, but also can realize the transmission of processor control signals and enable signals using 422 by adding a functional adapter board with RS-422 transceiver chip.

[0034] The utility model adopts an integrated design for the RF receiving channel and the RF transmitting channel, which combines the millimeter wave vertical interconnection technology and expands the space of the vertical plane. It can arbitrarily combine multiple transmitting channel modules, multiple receiving channel modules, or a combination of multiple transmitting channel modules and receiving channel modules, which effectively solves the interchangeability of multi-channel transceiver modules and realizes the miniaturization of the product. The technology also has an excellent reflection coefficient, widens the passband frequency of the local oscillator, and thus expands the working bandwidth of the system.

[0035] Embodiment 2:

[0036] An ultra-wideband multi-channel transceiver system, such as Figure 1As shown, it includes an RF transceiver channel component, a local oscillator power division network, a local oscillator module and a control module; the input ends of the power supply and control signals of the RF transceiver channel component are long pins of the RF glass insulator pins, which are connected to the pads on the control module with enameled wires. The beads on the side of the local oscillator module are welded to the pads on the control module for power supply and SPI control; the power supply and switch control signal of the local oscillator power division network are led out of the pads and connected to the corresponding pads on the control module with welding wires. The micro rectangular connector is connected to the corresponding pads on the control module with welding wires; an SMP male RF connector is sintered on the other side and welded to the corresponding pads on the control module for external output of a reference clock signal.

[0037] Preferably, in this embodiment, if Figure 1 As shown in the figure, the four-channel RF transceiver channel component is composed of separate small modules, and the RF link of each channel is divided into two sections between the two-stage mixers. The sections are connected by RF cables, so that the input and output ports of the RF transceiver channel are located on the same side. The entire multi-channel transceiver system has a total of 8 SMP RF ports on each side, which are the RF input and output ports of the four channels. Each of the two links of each channel requires a local oscillator signal, and the four channels require a total of 8 local oscillator signals. They are connected to the local oscillator power division network through the SMP RF connector in the vertical direction. The local oscillator power division network is designed to ensure that the two local oscillator signals of a channel are supplied at the same time, while taking into account the time-sharing operation of the system transceiver channel.

[0038] Preferably, if Figure 2 As shown, in this embodiment, the RF transceiver channel component passes the RF signal received by the antenna through a limiter first, so as to realize the anti-burning function of the receiving channel. The device selection needs to take into account the operating frequency, peak power and other requirements; then it passes through a filter for pre-filtering the received signal. The device selection needs to take into account the power capacity, the operating frequency of the receiving channel and the requirements of out-of-band suppression. According to the noise coefficient calculation formula of the cascade system, the noise coefficient of the first stage has the most important influence on the noise coefficient of the entire cascade system, so the first-stage amplifier should select a low-noise amplifier with low noise coefficient and high gain. The digitally controlled attenuator is used for link gain adjustment; the switching filter divides the ultra-wideband into multiple frequency bands, switches the corresponding channels according to different receiving frequencies, and the equalizer is used for amplitude equalization. The role of both is to achieve better flatness within the ultra-wideband; the link adopts two-stage frequency conversion to prevent harmonics and local oscillator leakage signals from mixing into the working frequency range. Mixer 1 performs up-conversion to move the received signal to a fixed high frequency outside the working frequency band, and then passes through a bandpass filter with this high frequency as the center frequency to filter out clutter; mixer 2 performs down-conversion to mix the fixed high frequency with the fixed frequency local oscillator signal to obtain the target intermediate frequency signal; after the intermediate frequency signal is amplified, it is finally passed through an LC bandpass filter to control the bandwidth of the intermediate frequency signal. Preferably, if Figure 3As shown, the link order of the RF receiving channel and the RF transmitting channel is opposite, the limiter is reduced, and the other devices are consistent. Furthermore, the power supply and control signal input ends of all active devices such as amplifiers, programmable attenuators, switch filters, etc. in the link of the RF receiving channel and the RF transmitting channel are led out with RF glass insulator pins. The positions of the pins of the two channels are exactly the same, and the cavity structure is also designed in a unified manner to achieve the interchangeability of RF transceiver channel components.

[0039] Preferably, all RF components adopt mature micro-assembly technology, and most of the selected chips are gallium arsenide (GaAs) semiconductor integrated bare chips, which have higher operating frequency, lower power consumption and low noise. The bare chips are installed by conductive adhesive bonding process and connected to the microstrip line by gold wire bonding.

[0040] Preferably, the local oscillator module provides a local oscillator signal for each RF channel with two frequency conversions. There are two types in total, one generates a variable frequency and the other generates a fixed frequency. To achieve the reception or transmission of independent local oscillators for each two channels, two local oscillator modules are provided for each type. The frequency synthesis function of the local oscillator module is mainly realized by the PLL chip LMX2595RHAT with integrated VCO, a frequency multiplier, a switch, and a filter. The local oscillator module is installed in the vertical direction of the power control board, and the lead-out glass beads are welded to the corresponding pads on the control board to obtain power supply, control signals, and 100MHz clock reference signals.

[0041] Preferably, the local oscillator power division network distributes the local oscillator signal generated by the local oscillator module, and uniformly controls multiple single-pole double-throw switches to select one channel, so as to provide the local oscillator signal only for the transmitting channel or the receiving channel at a certain time, so as to realize the time-sharing operation of the transceiver channel. The circuit layout of the local oscillator power division network and the selection of the switch device are completed when the arrangement of the RF transceiver channel components is determined, so for different transceiver combinations of the four channels, the local oscillator power division network needs to be adjusted accordingly.

[0042] Preferably, if Figure 4As shown, the level conversion chip on the control module converts the level of the external input power supply and supplies power to other modules. The control module is equipped with an independent level conversion chip for each module, and the power supply can be controlled by FPGA to control the working state of each module. The control module is mainly implemented by FPGA. In addition to controlling the power supply of all modules, FPGA also controls programmable devices such as digital attenuators, single-pole double-throw switches, and switch filters, and determines the functional state of the corresponding modules. Furthermore, there are two ways to control the working and functional state of the entire system. The first way is to control the attenuation value of the channel and the switching of the channel transceiver state by assigning the corresponding TTL level to the discrete port led out by FPGA; the second way is to use a functional adapter board with a 422 chip to achieve control through the 422 serial port.

[0043] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
