DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-frequency cutoff relay terminal and, more particularly, to a high-frequency cutoff relay terminal used in a bias circuit in which a high frequency superimposed on a bias line supplied to a high-frequency circuit is problematic. Related to high frequency circuits.

[0002]

2. Description of the Related Art As shown in FIG. 3, a conventional relay terminal has a relay terminal 1 for relaying a bias line and a ground terminal for fixing the relay terminal 1 to a conductor so as not to be grounded to GND.
It had a structure that could be fixed via an insulator or a dielectric 4.

[0003]

The conventional relay terminal is a terminal for relaying a bias wire used for supplying a bias to a high-frequency circuit, and the relay terminal body is superimposed on the bias supply line. There is no effect to cut the high frequency.

In general, a feedthrough capacitor has been used to cut such superimposed high frequencies. However, mounting the feedthrough capacitor requires a wall due to its structure.

[0005]

According to the relay terminal for high frequency cutoff of the present invention, the main body of the relay terminal is made of a capacitor, and the lower part of the capacitor as the grounding means is made of a screw-in type screw.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment of the present invention. The main body of the high frequency cut-off relay terminal is composed of a capacitor 2, and a relay terminal 1 for relaying a bias wire is provided above the capacitor 2, and a ground screw 3 for grounding is provided below the capacitor 2. It consists of

In the relay terminal of the present invention, since the relay terminal can be very easily and reliably mounted on a circuit board or the like by using the grounding screw, the applicable range is widened.

FIG. 2 is a diagram showing a high-frequency circuit using the relay terminal of FIG. 1, and a microwave IC (MI) is mounted on a circuit board 7.
C) 6 is attached, and a bias to this is supplied via the relay terminal 5. Reference numeral 8 denotes a bias line.

[0009]

As described above, the present invention has the effect of greatly attenuating the high frequency superimposed on the bias line when relaying the bias line by using the main body as a capacitor, and the ground is connected to the ground. Since the screws under the capacitors are used, mounting on any surface is possible if there are places where the screws can be tightened.
