[0022] Please see Figure 1-5 The embodiments of this utility model are described in detail below.

[0023] Example: A handheld radio with a portable radio range extender, see [link / reference] Figure 1 As shown, the device includes a power amplifier module 1, a handheld terminal module 2, a control module 3, and a power supply module 4. The power amplifier module 1 is connected to the handheld terminal module 2 via an RF cable and a data cable. The power supply module 4 is connected to both the power amplifier module 1 and the control module 3 to supply power to them. The control module 3 is connected to both the power amplifier module 1 and the handheld terminal module 2 to control their operation.

[0024] In one specific embodiment: the power amplifier module 1 includes a circuit consisting of a radio range extender 1-1 and a filter 1-2 connected in series. The radio range extender mainly amplifies the radio frequency signal, and the filter mainly filters out harmonics and unwanted spurious frequencies generated after amplification by the power amplifier. One end of the power amplifier module 1 circuit is connected to a transmit / receive switch 1-3, which is used to connect to the radio frequency port of the handheld radio module 2. The other end of the power amplifier module 1 circuit is connected to an antenna switch 1-4, which is connected to an antenna 1-5.

[0025] In one specific implementation: the radio range extender 1-1 consists of two attenuators and one amplifier; the first attenuator is a fixed attenuator with an attenuation of 6dB, used for high-power protection; the second attenuator is an adjustable attenuator with an attenuation of 5dB, used for gain adjustment; the third stage is an amplifier with a gain of 17dB.

[0026] In one specific implementation: the filters 1-2 are divided into three segments: 30MHz to 43MHz, 43MHz to 63MHz, and 63MHz to 88MHz.

[0027] In this embodiment, the radio range extender is equipped with a 170B handheld radio, which can achieve power amplification and long-distance communication; it is connected to the handheld radio via RF cable and data cable; the antenna interface of the radio range extender is the same as that of the handheld radio, and it is equipped with a 1.3-meter whip antenna, or it can be equipped with the original handheld radio antenna; the battery capacity is increased to meet the requirement of not less than the original handheld radio's battery life.

[0028] In this embodiment, the receiving path principle is as follows:

[0029] When the device is in receiving mode, the RF signal of 30MHz to 87.975MHz received by the radio range extender antenna is sent to the RF port after being switched between transmit and receive, and then sent to the handheld radio antenna port through the RF cable.

[0030] Principle of transmission pathway:

[0031] When the device is in transmit mode, the radio frequency signal from the handheld radio antenna port is sent to the radio range extender via the radio frequency cable. After being switched between transmit and receive, it is sent to the power amplifier module. The radio frequency signal in the power amplifier module is attenuated by a fixed attenuator and a controllable attenuator before being sent to the portable radio range extender for amplification. The amplified radio frequency signal is filtered to remove harmonics and unwanted spurious frequencies before being output through the antenna port.

[0032] In one specific implementation: the power module 4 consists of a DC / DC conversion circuit and a switching circuit; wherein, the DC / DC conversion circuit converts 14.4V voltage into ±3.3V, +5V and +24V voltages, wherein +5V and +24V voltages are used to power the power amplifier module 1, +3.3V is used to power the control chip in the control module 3, and -3.3V and +24V are used to power the control circuit.

[0033] In one specific implementation: the control module, based on the GD32 hardware platform, implements the following functions in C language: communicating with the handheld radio module; controlling the filter band; controlling the transceiver path and the transceiver indicator light; storing power parameters, etc.

[0034] This handheld radio power amplifier module enhances the transmit and receive signal strength of handheld radios, ensuring stable and clear signals even at long distances or in weak signal environments. It also improves signal interference resistance, amplifying useful signals and improving communication quality in complex areas with electromagnetic interference. The handheld radio is highly portable, with a lightweight and easy-to-carry design that increases the radio's operating frequency. Furthermore, it improves the reliability of emergency communications, extends battery life, and reduces power consumption by maintaining effective communication even in low-power mode due to the enhanced signal strength. Finally, it is cost-effective, offering a more economical and efficient solution compared to replacing the handheld radio with a higher-power one, significantly improving the performance of existing equipment.

[0035] After production, this product can be used by emergency management departments for emergency rescue, in natural disaster sites such as earthquakes, floods, and fires, or in urban emergencies. It can also be used by outdoor brands for promotional purposes at large-scale outdoor events, and for outdoor adventure activities such as mountaineering, hiking, and camping. Furthermore, it will be incorporated into the development of maritime communications, providing crucial support for field exercises, urban warfare, border patrols, and air-to-sea communications. Therefore, its application scope is broad.
