... The start-up time of the oscillator determines the maximum data rate that the transmitter can send. DESIGN HINT “Using the RCT-433-AS with a microcontroller UART”: Data should be inverted when using the transmitter with a UART. The normal marking state of a UART is a logic 1, which will cause constant transmission ...

... Power Supply The RCT-433-AS is designed to operate from a 1.5 -12V power supply crucial that this power supply be very quiet. The power supply should be bypassed using a 0.01uF low-ESR ceramic capacitor and a 4.7uF ceramic capacitor. These capacitors should be placed as close to the power pins as possible ...

... For example, the cut-off for a 433.92 MHz module would be about 470 MHz. DESIGN HINT “T-Pad”: The RCT-433-AS transmitter can be sensitive to unbalanced or unmatched loads and could fail to operate or operate intermittently in this condition. Try to match your antenna load as close to 50 ohms as possible. Use a T-pad if necessary to give the transmitter a close 50 ohm match before your antenna ...
