โมเด็มข้อมูล RF / ตัวส่งและตัวรับสัญญาณไร้สาย (200MW-SW)

200MW-SW Feature
Low cost, high speed
GFSK modulation mode, half-duplex
ISM frequency band: 433/490MHz, 315/868/915MHz should custom made
Transmission power: 200mW(23dBm)
Receiving sensitivity: -124dBm
Transmitting current: ≤ 250mA
Receiving current: ≤ 30mA, sleeping current <10uA(must custom made as TTL)
The standard 200MW-SW configuration provides 8 channels, to meet the multiple communication combination mode of the users
Even for semi duplex communication, the user doesn't need to prepare excessive programs, only receiving/transmitting the data from the interface. 200MW-SW will automatically complete the other operations, such as transmission/receiving conversion in the air, control etc.
It has baud rate to be chosen such as 1.2kbps-9.6kbps. User can change it via software.
Transmitting distance can range about 2km (200mW) in the open air if the antenna is 2m high.
