摘要： The invention provides a small-sized low-cost spread spectrum communication device (1) including a narrow-band interference signal elimination circuit (5) capable of covering all the frequency band of a spread signal. A spread signal is received by an antenna (2) and supplied to a level detection circuit (10) via a variable amplifier (8) and a divider (9). The level detection circuit (10) controls the variable amplifier (8) so that the spread signal is amplified to a fixed level. The signal containing a narrow-band interfering signal is then passed through a plurality of magnetostatic filters (11, 12, 13) connected in series such that the saturation level thereof successively decreases, thereby limiting the narrow-band interfering signal having a level greater than the level of the spread signal in a step-by-step fashion. Thus, the narrow-band interfering signal contained in the spread signal is limited to a low level without encountering a significantly large incidental reduction in the spread signal. The narrow-band interference signal elimination circuit (5) according to the invention may be realized in the form of a small size.

摘要： An S/N enhancer (100) is provided which can be formed to be small in size and in which impedance matching can easily be achieved. The S/N enhancer (100) includes two magnetostatic wave elements (12a,12b). First to fourth transducers (20a, 22a,20b,22b) each in the shape of a single line are disposed on YIG thin films (16a,16b) of the magnetostatic wave elements (12a,12b) in parallel and spaced from one another. An input terminal (24) is connected to one end of the first transducer (20a). An attenuator (28a) is connected between the other end of the first transducer (20a) and one end of the third transducer (20b). A 180° shifter (38) and another attenuator (28b) are connected in series between one end of the second transducer (22a) and one end of the fourth transducer (22b). An output terminal (26) is connected to the other end of the fourth transducer (22b). The other ends of the second and third transducers (22a,20b) are respectively grounded.
