RE: US5MSQ - transceiver

Diplekser nie załatwi problemu. Tutaj diplekser z filtrem dolnoprzepustowym
http://www.changpuak.ch/electronics/calc_18.php
Selektywność to tłumienie sygnałów będących poza pasmem filtru Rx , ale będących w jego pobliżu -Januszu to tak miejwięcej jak w homodynie z lustrzanką i dlatego napisałem o obu problemach. Moim zdaniem bardziej przeszkodzi lustrzanka niż sygnały leżące powyżej częstotliwości odbieranej -wystarczy spojrzeć na charakterystyki filtrów z przełączanymi pojemnościami -ale ja bawiłem się piligrimem. Podaj większy kawałek schematu i zaznacz ten fragment na czerwono.
