摘要： An active filter (100) is disclosed with improved blocker signal rejection characteristics. Linear resistors, such as fixed value resistors (3, 4) are used at the input stage (72) of the filter (100) to suppress any blocker signal. A gain compensation stage (57) is added to the output stage (23) using resistors (24) fabricated with the same technology used to fabricate the input resistors (3, 4) in order to offset any gain changes associated with the input fixed value resistors (3, 4). In an exemplary embodiment, the fixed value resistors (3, 4) are fabricated using polysilicon.

摘要： A filter circuit extracts a desired signal in the presence of interference by using a variable gain circuit whose input is the frequency converted received signal and whose output is fed through an active filter to produce the desired signal. The signal levels before and after the active filter are detected and the higher level is used to control the gain of the variable gain circuit.

摘要： A transmitting apparatus which can suppress unnecessary power consumption. An optimal signal line is selected from a plurality of signal lines (53-56) having different gains provided by respective signal amplifying devices to perform gain adjustment on a signal to be transmitted, which is supplied to an input terminal (58), so as to optimize power consumption of each signal amplifying device in accordance with a gain value, and to halt the operation of the signal amplifying device on a signal line which is not selected. Therefore, unnecessary power consumption can be suppressed.
