    • A substrate (10), a first mold (200) and a second mold (250) are prepared, and a plurality of switch patterns (14), (18) are provided by providing openings (pattern-removal portions) (A) in such a manner that a pattern (11), which has been formed on the surface of the substrate (10), is divided into a plurality of patterns to form A switch substrate. Next, the switch substrate (1) is clamped between the first mold (200) and the second mold (250). At such time, the side of the switch substrate (1) provided with the switch patterns (14), (18) is brought into surface contact with an abutting surface (201) of the first mold (200) and, at the same time, a cavity (253) provided in the second mold (250) opposes the other side of the switch substrate. Next, a molten molding resin is charged into the cavity (253) provided in the second mold (250) to thereby fill the cavity (253) and the openings (A) of the substrate with the molding resin. After the molding resin hardens, the first mold (200) and the second mold (250) are separated and the switch substrate (1), which will have the molding resin case 40 attached thereto, is extracted.
    • 制备基板(10),第一模具(200)和第二模具(250),并且通过提供多个开关图案(图案去除部分)(A) 已经形成在基板(10)的表面上的图案(11)被分成多个图案以形成A开关基板的方式。 接下来,将开关基板(1)夹在第一模具(200)和第二模具(250)之间。 此时,具有开关图案(14),(18)的开关基板(1)的一侧与第一模具(200)的抵接面(201)表面接触,并且同时 设置在第二模具(250)中的空腔(253)与开关基板的另一侧相对。 接下来,将熔融成型树脂装入设置在第二模具(250)中的空腔(253)中,从而用模塑树脂填充基板的空腔(253)和开口(A)。 在模制树脂硬化之后,分离第一模具(200)和第二模具(250),并且将具有附着于其上的模制树脂壳体40的开关基板(1)被提取。

    • A digital radio-relay system has a transmitting terminal station, at least one repeater station a receiving terminal station, a non-regenerative repeater station which does not regenerate a digital signal in order to simplify and reduce cost of the system, while keeping excellent signal quality in transmission. Each repeater station has a plurality of sub-units relating to respective sub-system signals each having a plurality of carriers so that the frequency spectrum of each sub-system signal is allocated on a frequency axis based upon a frequency division multiplex system. A repeater station having a first frequency converter to convert a received radio frequency to IF frequency, bandpass filters for deriving one of the carriers in each sub-system signal, amplifiers to amplify the derived carrier on IF band stage, and a second frequency converter to convert the IF frequency to radio frequency, has a common reference oscillator which generates a reference frequency which is a common divisor of all the local frequencies for all the radio frequencies of all the sub-system signals. Only one of an upper and lower heterodyne signals is taken in all the frequency conversions, so that distortion in each relay section is added in-phase. Leaked noise caused by the bandpass filters is added to original carrier in-phase. All the distortion thus added in the relay sections can be compensated by a transversal equalizer in the receiving terminal station. Therefore, excellent signal quality is obtained although a simple non-regenerative repeater station is used.
    • 数字无线电中继系统具有发送终端站,至少一个中继站,接收终端站,不再生数字信号的非再生中继站,以便简化和降低系统的成本,同时保持优良的信号 传输质量。 每个中继站具有与分别具有多个载波的各个子系统信号相关的多个子单元,使得每个子系统信号的频谱基于频分多路复用系统被分配在频率轴上。 一种具有第一频率转换器以将接收到的射频转换成IF频率的中继站,用于导出每个子系统信号中的一个载波的带通滤波器,用于在IF频带级上放大导出载波的放大器,以及第二频率转换器 将IF频率转换为射频,具有公共参考振荡器,其产生作为所有子系统信号的所有无线电频率的所有本地频率的公约数的参考频率。 在所有频率转换中仅采用上外差信号中的一种,因此每个继电器部分的失真同相加法。 由带通滤波器引起的泄漏噪声被同时添加到原始载波。 所以在继电器部分中增加的所有失真都可以由接收终端中的横向均衡器补偿。 因此,虽然使用简单的非再生中继站,但是获得了良好的信号质量。
