patch module 455-535MHz transceiver bidirectional amplifier

patch module 455-535MHz transceiver bidirectional amplifier Description

The built-in intelligent receiving/sending discrimination circuit does not require front-end equipment to provide receiving/sending switching control signals.
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.
The transmission gain is manually adjustable, which is convenient for compatible wireless devices with different transmission powers.
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.
Compatible with various modulation methods such as LORA and FSK/ASK/OOK/MSK/GFSK.

Description:
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.
(Note: Hand-held walkie-talkies cannot use this module to achieve the purpose of extending the transmission range due to their high transmission power.)
