【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、電力増幅装置に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a power amplifier device.

た。Conventionally, high-frequency power amplifiers have been used to amplify the high-frequency power of microwave communication devices, but with the miniaturization and integration of microwave communication devices, G
High frequency power amplifiers using aAsFETs and the like have been developed. However, due to the miniaturization and integration of this power amplifier, power is concentrated in one part, and the heat generated there is preventing high-density integration and high output. As this heat dissipation means, a heat dissipation device is provided which is made of a metal such as aluminum and has fins so as to provide a heat dissipation area directly under the solid element portion. In addition, a method was adopted to increase heat dissipation efficiency by using forced air cooling using a fan or the like.
しかしながら、従来の放熱手段は、集中した熱を拡散す

高周波電力増幅器は、その大きさがアンテナの特性に大
きく影響し特性劣化を招く欠点がある。However, in conventional heat radiating means, the heat radiating area of the radiator is made as large as possible in order to diffuse the concentrated heat, which increases the weight and shape of the device, which hinders miniaturization of the device. In particular, a high frequency power amplifier installed opposite to an antenna for outdoor use has the disadvantage that its size greatly affects the characteristics of the antenna, leading to deterioration of the characteristics.

and a heat pipe 1 connecting the two. Further, the heat input section 2 of the heat pipe 1 is provided as close as possible to the power amplifier 6A in the high frequency amplification section 6. The heat radiator 3 of the heat pipe 1 serves as a radiator 7. Here, the heat generated by the power amplifier 6A is transferred to the heat sink 7 via the heat pipe 1.
heat is transferred to and dissipated. It should be noted that by providing a plurality of heat input sections 2 as necessary, the entire power amplifier 6A absorbs heat.

When one end of the heat pipe is a heat input section 2 and the other end is a heat dissipation section 3, when heat is applied to the heat section 2, the catalyst evaporates and becomes a heat transfer flow 5, which flows toward the heat dissipation section 3. Heat is transferred to. Heat is transferred at a speed several hundred times faster than that of copper, which is said to have good thermal conductivity at the speed of sound. The transferred heat is radiated by the heat radiating section 3, the catalyst is liquefied, and the liquid is refluxed to the heat input section 2 through the liquid source section 4.

ンテナ９の放射電波を妨害することがない。FIG. 3 shows a configuration diagram in which this embodiment is applied to a high frequency power amplification section attached to the back of a primary radiator of an outdoor antenna. The configuration of FIG. 3 includes an antenna 9, a high-frequency power amplification section 6 that transmits and receives high-frequency power to and from the primary radiator of this antenna, a column 8 of the antenna 9, a radiator 7, a high-frequency power amplification section 6, and a radiator. This is an embodiment in which the heat pipe 1 is connected to the heat pipe 1. Now, when the antenna 9 becomes smaller, the amount of heat dissipated by increasing the output of the high frequency power amplifying section 6 is transferred to the radiator 7 by the heat pipe 1. Therefore, this can be dealt with by increasing the size of the heat radiator 7, which has no space limitations. Further, since the high frequency power amplifying section 6 can maintain a small size, it does not interfere with the radio waves radiated from the antenna 9.
