MIniature Wireless Transceiver with RS-485 interface for Telemetry

[dimachorny]

Hello,

I need a solution for wireless telemetry data transmitting with following requirements:
1. Input and output terminals are RS-485 half duplex
2. Data rate: ASCII 10 bytes, up to 500 samples per second
3. Transmitting range: up to 50 meters
4. Voltage supply: 7.4 or 3.7 volts (nominal)
5. Size/Volume limitations for transmitter: don't exceed 25x40x10 mm
6. 433 MHz band preferable (anyway must meet european regulation requirements)
7. The data stream is:
Output device RS-485 --> Transmitter --> Antenna --> Wireless com --> Antenna --> Receiver --> RS-485 Input device

Any suggestion is appreciated,
Thank you
