Title:
CASCADED DIPLEXER CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2014/022147
Kind Code:
A3
Abstract:
A cascaded diplexer circuit provides a diplexer leg with selectable passbands. The cascaded diplexer circuit has a diplexer with a plurality of first bandpass filters. A second bandpass filter is selectively switched in series with one of the first bandpass filters. Preferably, the passband of the second bandpass filter is chosen to limit the passband of the first bandpass filter, such that when the second bandpass filter is switched into the circuit, the passband of the diplexer leg is reduced. In some embodiments, the passband of the second bandpass filter is a subset of, or overlaps with, the passband of the first bandpass filter.
