APPLICATION NOTES
If the input is FM or FSK modulation, whether the IF input is a balanced or an unbalanced input, there is no problem. But,
if the input is ASK modulation and the IF input is a balanced input, the Bit Error Rate (BER) may be high. Therefore, if
the input is ASK modulation, the IF input must be an unbalanced input. If the input is an unbalanced input as shown below,
do not terminate Pin 1 (do not connect the bypass capacitor between Pin 1 and GND). If Pin 23 is the input do not terminate
Pin 2.
