Systems and methods for communication system having improved transmitter and/or receiver performance. The invention may include systems and methods related to the use of non-superconducting and/or superconducting filters for a receiver and/or a transmitter. The invention is particularly useful in electronic communication systems that have heavy usage and requiring accurate and sharp channel filtering, for example wireless communication systems. In various embodiments, a receive filter network may include a non-superconducting filter and/or a superconducting filter. In various embodiments, a transmit filter network may include a non-superconducting filter and/or a superconducting filter. The superconducting filter(s) may be, for example, a band pass filter and/or a notch filter or band reject filter.
