Switch arrangement for use in circuit device that is utilized in e.g. transmitter for wireless transmission of data, has inductors arranged parallel to lines and operable to capacitances in fixed frequency range, respectively

摘要

The arrangement has a line (A) arranged between first and second terminals (10, 20) and comprising a switch (S1) with a parasitic capacitance (C1). Another line (B) is arranged between the first terminal and a third terminal (30) and comprises a switch (S2) with a parasitic capacitance (C2). Inductors (L1, L2) are arranged parallel to the lines and operable to the capacitances in a fixed frequency range, respectively. A third line (C) is arranged between the second terminal and a fourth terminal (40) and comprises a switch (S3) with a parasitic capacitance (C3). An independent claim is also included for a circuit device comprising a filter.
