Signal handling apparatus for improving the linearity of the radio frequency circuit

摘要

small size, but also conform to the preferred integrated circuit (IC) and printed circuit board technology, while applicable to a wide operating frequency and bandwidth, a signal processing apparatus to provide high linearity. In one implementation, the signal handling device (100) receives an input signal, the input impedance transformer for matching the internal device impedance (102), divider for providing the N number of divided signal (104) , a plurality of signal processing circuits for processing the N number of divided signals (110; 112-1, ..., 112-m) and, combiner for the combined signal by combining the N divided signals includes a (120), the output impedance transformer for matching the output impedance of the device internal device impedance receives the combined signal and a (122). The apparatus filters, may provide duplex processing, and other high-frequency signal processing functions. An adjustable duplexer may be implemented using vector inductor and an adjustable capacitor array comprising a frequency dependent impedance transformer.
