• Manufacturer Part Number: RX3A-868.30-10
• Description: RECEIVER, 868.3MHZ
• Manufacturer: RADIOMETRIX

Functional description
The TX3B transmitter module uses a frequency modulated crystal-locked PLL and operates
between 2.9V and 16V at a current of 14mA nominal. At 3V supply it delivers nominally 9dBm
(8mW) RF output. The SIL style TX3A measures 32 x 12 x 3.8 mm, excluding pins.
