    摘要： A millimeter wave module includes a silicon substrate with first and second cavityes formed by anisotropic etching on the silicon substrate , and a glass substrate having a microstrip filter pattern and microbumps for connecting the glass substrate to the silicon substrate. A filter is provided using an air layer as a dielectric disposed in the first cavity. An MMIC is mounted by the flip chip method over the second air layer. A coplanar waveguide is on the silicon substrate for connecting the filter and MMIC. The filter having low loss is achieved because it has the microstrip structure using air as an insulating layer. Also change in characteristics of the MMIC during mounting is eliminated because the MMIC is protected by contacting air. Accordingly, the millimeter wave module has excellent characteristics and is made using a simple method.

    摘要： The present invention has a purpose to obtain an FSK data receiving system which is capable of constituting a direct-conversion receiver suitable for realizing an integrated circuit, is capable of decoding in a wide receiving band width, and is capable of realizing a small-sized and less-electric power consumption data receiving. The FSK-modulated local oscillator signal 3 is applied to the local oscillator 2, and there is provided the decode circuit 15 which obtains the decode signal 14 by judging whether the FSK-modulated frequency deviation of the carrier wave signal 1 is a positive deviation or a negative deviation on the basis of the comparison result of the voltage change in the frequency-voltage conversion circuit 16 for the base-band signal 8; i.e. the output signal of the frequency mixer 6. The offset amount of the local oscillator frequency is judged by the voltage judging means 17 to produce the control signal 18, And further, there is provided the another decode circuit 22 which makes the judgement of frequency change of the base-band signal 8 and the judgement of in-phase/opposite-phase relationship from the decode signal 14 and the output of the voltage judging means 17 so as to obtain the decode signal 23. Moreover, there is provided the decode signal processing circuit 25 which obtains the decode signal 24 from the decode signals 14, 23 in response to the control signal 18.
