Features

F Ground RF connection to radio module RF Ground NOTES: 1. This amplifier expects a 100mW power level to be output from the radio on transmit. 2. The TXE line should be tied to the TR2M TXE input. When this line is asserted (low) the amplifier is turned on (drawing 280-300mA) and the RF switching connects it between the module and the aerial. When it is inactive (high or floating) a low loss path is provided for the rx signals, from aerial to the module. 3. If a low power transmit mode is needed, the receive path is bidirectional, and capable of carrying up to 100mW of power. In this case the.
