- FIG. 1 is a perspective view of a high-frequency module 100 according to an embodiment of the present invention.
- the high-frequency module 100 of the present invention has a first high-frequency circuit 5 and a second high-frequency circuit 6.
- the first high-frequency circuit 5 of the present invention includes a mixer circuit 12 and a first filter circuit 16 mounted on a first circuit board 201, and a metal case 4 covering the first circuit board 201 so as to cover them. Mounted on top of 201.
- FIG. 2 shows an enlarged side view of the high-frequency module 100.
- An end face electrode 7 is formed on a side surface of the first circuit board 201.
- the GND electrode of the end face electrode 7 and the terminal 3 formed on the metal case 4 are electrically connected with solder 8 to make the high frequency module 100 high. It has a configuration in which frequency noise is shielded.
- the second filter circuit is mounted on the second circuit board 202, and like the first high-frequency circuit 5, metal is applied so as to cover the filter circuit components. Case 4 is attached.
- FIG. 3 is a top view showing the configuration of the high-frequency module 100
- the first high-frequency circuit 5 and the second high-frequency circuit 6 are mounted on the mother board 1, and
- the high frequency circuit of the present invention is configured by connecting the two at a high frequency with the signal line 10.
- connection line is configured as a 50 ⁇ impedance line, and a GND pattern 9 is formed around the signal line so that the signal line is not affected by noise, thereby ensuring the characteristics of the high-frequency module.
- a baseband signal of 380 MHz output from the baseband unit 3 1 and a local signal of 760 MHz output from the oscillator 41 are input to the mixer circuit 12, and are input to the mixer circuit 12.
- the signal is input to the first filter 13 via the matching unit 14 forming the first filter circuit 16. Since the first filter 13 uses a dielectric filter having a large noise removal performance for a low-power signal, the spurious signal output from the mixer 122 at 250 MHz is reduced to 50 dB. It can be attenuated and output to the matching unit 15.
- the spurious signal radiated from the input-side matching box 14 jumps through the first filter 13 and is input to the output-side matching box 15 is attenuated by 60 dB or more, and is attenuated by the first filter circuit 16.
- An amount of 50 dB can be secured.
- the output signal from the matching unit 15 is converted to the second filter of the second high-frequency circuit 21.
- a signal that has been input to the matching device 23 forming the circuit 19 and that has been subjected to impedance matching to the second filter 22 is input.
- the second filter 22 a dielectric filter having a large noise removal performance for spurious signals is used.
- the spurious signal of 380 MHz output from the mixer 12 is attenuated by 50 dB and output to the matching unit 24.
- the spurious signal of the local signal that is radiated from the matching box 23 on the input side and jumps over the second filter 22 and is input to the matching box 24 on the output side is attenuated by 60 dB or more.
- it radiates from the input-side matching box 14 of the first high-frequency circuit 11 and hops through the first filter 13, the matching box 15, the matching box 23 and the second filter 22, and the output-side matching box.
- the spurious signal due to the oral signal input to 24 is attenuated by 110 dB or more. As a result, it is possible to secure an attenuation of 50 dB by the second finoleter circuit 19.

- the light is radiated into the air from the antenna 63 through the end part 62.
- This wireless device has a large spurious signal attenuation characteristic because the high-frequency module 100 of the present invention is used, and the spurious signal radiated from the antenna 63 becomes small, so that a wireless device with a small spurious signal is used. Can be configured. Industrial applicability
- the high-frequency circuit is divided into two parts, the first filter circuit is arranged in the first high-frequency circuit, and the second finoleta circuit is arranged in the second high-frequency circuit. This makes it possible to provide a high-frequency module having a small spurious signal output.
