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.
