<p>A receive front-end useful for receiving a communication signal includes a bandpass filter having a high selectivity for selecting a passband of the communication signal, an equalizer to compensate for group delay variance introduced by the high selectivity of the bandpass filter, and a low noise amplifier protected by the bandpass filter from signals outside the passband and coupled to the equalizer to establish noise figure for the receive front-end. The filter may be self-equalizing to provide all or a portion of the requisit delay compensation, and both the filter and the equalizer may include high-temperature superconducting components.</p> |
