... RCT-433-ASBR DATASHEET 1. Description The RCT-433-ASBR is ideal for remote control applications where low cost and longer range is required. The transmitter operates from a 1.5-12V supply, making it ideal for battery-powered applications. The transmitter employs a SAW-stabilized oscillator, ensuring accurate frequency control for best range performance. Output power and harmonic emissions are easy to control, making FCC and ETSI compliance easy ...

... The start-up time of the oscillator determines the maximum data rate that the transmitter can send. Design Hint (Using the RCT-433-ASBR 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-ASBR 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 ...

... RCT-433-ASBR DATASHEET Design Hint (T-Pad): The RCT-433-ASBR 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. A T-pad will also act as an attenuator. See figure 6 below, for a T-pad match/attenuator circuit ...

... Pin 4 provides operating voltage for the transmitter. VCC should be bypassed 4 VCC with a .01uF ceramic capacitor and filtered with a 4.7uF tantalum capacitor. Noise on the power supply will degrade transmitter noise performance. Table 1, Pin Descriptions 3.2.

... RCT-433-ASBR DATASHEET 4. Reflow Profile The RCT-433-ASBR is suitable for reflow ovens and heat guns. To prevent damage to the module through excess heat, the reflow oven temperature profiling is very important. A suggested oven profile is detailed in table 2 below. Steps are: First, preheating shall be fixed at 140 – 160 degrees Celsius for seconds. Then ascending time to preheating temperature 150 degrees Celsius shall be 30 seconds minimum. Last, heating shall be fixed at 200 degrees Celsius for 50 – ...
