Block downconverter using a SBAR bandpass filter in a superheterodyne receiver |
摘要 |
Several embodiments of a block downconverter using a SBAR bandpass filter in a superheterodyne receiver are disclosed. The block downconverter is coupled to receive a radio frequency input that includes a target region. The block downconverter is configured to produce a selected one of an overlapping plurality of portions of the target region as an intermediate frequency (IF) block having a fixed center frequency. Furthermore, the block downconverter includes a semiconductor bulk acoustic resonator (SBAR) filter that operates as an IF filter.
