R1 Single frequency repeater Specification.pdf

Work function

The repeater can configure the transceiver frequency according to the needs of the scenario, and the transceiver frequency does not affect each other. The repeater has a radius of 4-5 kilometers (outdoor), which can expand the communication area of ordinary handsets by 2 times. Depending on the scenario, the repeater can be placed at a high center to cover the whole world or at a tunnel bend to connect the two ends, and the repeater will forward the legitimate call to other devices after receiving the legitimate call (as shown on the left side of the figure).

Multiple repeaters(SPECIAL version) can be attached to the LAN. For example, 1 repeater is placed on each floor of a building. When a handset initiates a call, the voice will be transmitted to the entire LAN through the network and forwarded by other repeaters, so as to complete the signal coverage of the entire building. The special feature of this machine is that the entire building can be covered with only one frequency point.

Product Advantages:

1. The circuit adopts the classical superheterodyne architecture, with voltage controlled bandpass filter, dedicated receiver, dedicated PLL, and crystal IF filter. All RF components come from TI, AKM, SKYWORKS, KDS and other international first-class suppliers. The performance is better than that of zero-IF integrated RF solutions.

2. The all-aluminum body and good thermal design ensure long-term high-load operation.

3. 400-470 full section work. Compatible with Motorola and Hytera machines.

4. Optimized for small mounting scenarios, strong anti-interference; leading standby power consumption and weight.

5. Digital signal transmission is used in the whole process of audio forwarding to avoid the loss of sound quality caused by analog audio forwarding.

6. Compared with the traditional frequency repeater, this product does not need to reprogram the handset, and still works in DMO mode. Even if the repeater signal range is out of range or the repeater fails, the call between the handset is still valid – making the communication more reliable.
