Systems and methods for an upgradeable and/or reconfigurable receiver are
provided. In general, the present invention is directed to providing
systems and methods for designing an electronic communication system
having easy and cost effective upgradeable receiver systems and
components including, for example, an amplifier and/or a filter. For
example, a receiver may include a receiver front end that is configured
so that at least one of the original conventional system components may
be used along with one or more new system components to provide greater
receiver sensitivity and/or selectivity. In various embodiments, portions
of an upgradeable receiver system may be made as modular components that
allow easy replacement for the upgradeable components which may include a
signal amplifier and/or a signal filter. In various embodiments the
receiver may be upgraded by replacing a conventional low noise amplifier
(LNA) with a high temperature superconductor (HTS) filter and/or a
cry-cooled LNA.
