Abstract: A transponder includes a notch filter to suppress the 1300 MHz at minimal product cost increase. The notch filter utilizes a printed transmission line length adjusted to a correct length. This notch filter will connect to the antenna matching circuit at a junction between the antenna and an ASIC as a shunt component with high impedance (e.g., greater than 500 Ohms) at 915 MHz and low impedance (e.g., less than 10 Ohms) at 1300 MHz.
