RE: US5MSQ - transceiver

"Chodzi mi o polepszenie selektywności. Tylko, żeby nie było przerostu formy nad treścią."

Selektywność to tłumienie sygnałów będących poza pasmem filtru Rx , ale będących w jego pobliżu. Decyduje o tym stromość filtru , który posiada odbiornik. Tłumienie częstotliwości lustrzanej to oddzielny parametr . Jeśli chcesz Marku uzyskać lepszą selektywność w homodynie to proponuję wykonać LPF zbudowany z elementów LC.. A diplexer tak jak napisał Rafał stosuje się w innym celu. Pozdrawiam.
