B3 20W Electronic Fence RF Amplifier Module with LNA

The ZDTECH B3 20W electronic fence RF amplifier module is an RF component designed for a specific frequency range with excellent performance and multiple functions. The module contains a transmitting channel (PA) and a receiving channel (LNA), and its operating frequencies are 1805-1880MHz and 1710-1785MHz respectively.

In terms of transmission, the module is able to output up to 43±1dBm power and has a gain of 50±1dB, while the gain adjustment range is ≥25dB and the minimum gain adjustment step is 1dB. In addition, it also supports automatic level control (ALC), a fluctuation range of ≤2.0dB, and an adjacent channel power ratio (ACPR) of ≤-45dBc to ensure signal stability and purity.

In terms of reception, the module has a gain of 25±1dB, and also supports a gain adjustment range of ≥25dB and a minimum adjustment step of 1dB. Its noise figure is ≤1.8dB and the maximum input level is 0dBm, which ensures the receiving sensitivity in a weak signal environment. In addition, the module also has excellent out-of-band spurious suppression capability, and the spurious response in the 9kHz~1GHz and 1GHz~12.75GHz frequency bands is ≤-36dBm/30kHz and ≤-30dBm/30KHz respectively.

The operating voltage of the module is ≤3.5A/DC+28V, and the operating temperature range is -25~+55℃, which is suitable for various harsh environments. The RF port adopts MCX-KHD and SMA-KHD interfaces, which are convenient for connection with different devices. At the same time, the module also provides a 5569 connector as a power connector, which has the characteristics of 4.2MM spacing and 2*3PIN bent needle seat.

In order to realize the monitoring of the working status of the module, the module also provides an RS485 monitoring interface, which supports 9600/19200 optional baud rate (default 19200). Its size is 130x110x21mm, which is compact and lightweight, and easy to integrate into various systems.

In conclusion, the B3 20W electronic fence RF amplifier module has excellent performance, multiple functions and good adaptability, and is an ideal choice for RF applications such as electronic fence systems.
