AB-IOT-510 Patch Module 455-535MHz Transceiver Bidirectional Amplifier 510M Gain Adjustable Amplifier Module

The built-in intelligent receiving/sending discrimination circuit does not require front-end equipment to provide receiving/sending switching control signals.<br> The module works in the receiving state by default and amplifies the received signal. When the front-end equipment is detected to transmit external signals, it will instantly switch to the transmitting and amplifying state.<br> The transmission gain is manually adjustable, which is convenient for compatible wireless devices with different transmission powers.<br> The receiving/sending link has a high degree of isolation, and the receiving link can withstand strong external interference without causing self-excitation of the loop.<br> Compatible with various modulation methods such as LORA and FSK/ASK/OOK/MSK/GFSK.<br> AB-IOT-510 series two-way signal amplification modules are designed for various applications in the 510M (470MHz-520MHz) frequency bands. Its compact size and convenient use make it easier to design products for high-power and long-distance applications in this frequency band.<br> (Note: Hand-held walkie-talkies cannot use this module to achieve the purpose of extending the transmission range due to their high transmission power.)<br> Parameter:<br> Working frequency band: 470MHz-520MHz<br> Receiving gain: 11dB±2dB<br> Receiving noise figure: less than equal 2.0dB<br> Transmission gain: 5dB-11dB (±2dB) adjustable<br> Recognition threshold for receiving and sending switching: -2dBm<br> Input power range: 1dBm-25dBm<br> Work status LED indication:<br> Receiving status: green light is on, blue light is off<br> Transmitting status: blue light is on, green light is off<br> In TDD working mode, the blue light and green light will flash alternately<br> Colour:As Shown<br> Material:plastic+metal<br> Package Contents:<br> 1 * patch Module<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
