Methods and systems for a switchable diplexer with physical layout to provide isolation may comprise a diplexer comprising bandpass filters, the bandpass filters having a predetermined passband, and switches coupled to the passband filters and configured to select one of the plurality of bandpass filters, where the bandpass filters are arranged in groups of bandpass filters, a first with an E-band bandpass filter with a passband between 475 MHz and 675 MHz and an F-band bandpass filter having a passband between 650 MHz and 875 MHz, the E-band and F-band bandpass filters being electrically arranged in parallel relation to one another, and a second comprising a D-band bandpass filter with a passband between 1125 MHz and 1675 MHz and a D-low band bandpass filter with a passband between 1125 MHz and 1225 MHz, the D-band and D-low band bandpass filters being electrically arranged in parallel relation to one another.

Switchable diplexer with physical layout to provide improved isolation

A switchable diplexer includes a plurality of bandpass filters having passbands for the frequency bands in which communication across a communication channel is desired. The bandpass filters can be arranged in groups of bandpass filters located adjacent to one another physically. Further, a group of bandpass filters can include a plurality of bandpass filters having a stop band in a common frequency range of interest. A plurality of switches can be provided to switch the desired bandpass filter into the circuit to allow communication on its corresponding band. The switches can therefore be electrically coupled to the passband filters and configured to select one of the plurality of bandpass filters for signal communication on the communication channel.
