摘要:
In a high-frequency circuit module, a resistance film (7a) is formed on a side of a semiconductor circuit chip (6), mounted above a dielectric substrate (1) through a ground metal layer (4), facing the dielectric substrate. A distance from the ground metal layer (2) to the resistance film (7) is a 1/4 wavelength at a predetermined frequency, and the resistance film has a sheet resistance equal to a characteristic impedance of air. A second dielectric substrate (12) with a metal layer (13) formed on a side opposite to the resistance film (7a) can be mounted. When being adhered to the second dielectric substrate (12), the resistance film (7a) has a characteristic impedance determined by a permittivity of a material of the semiconductor circuit chip (6). When it is formed spaced apart from the semiconductor circuit chip, the resistance film has a sheet resistance equal to a characteristic impedance of air. The thickness of the second dielectric substrate is a 1/4 wavelength in a desired frequency.
摘要(中):
在高频电路模块中,电阻膜(7a)形成在半导体电路芯片(6)的一侧,通过接地金属层(4)安装在电介质基片(1)的上方,面对电介质基片。 距接地金属层(2)至电阻膜(7)的距离为预定频率的1/4波长,电阻膜具有与空气的特性阻抗相等的薄层电阻。 可以安装具有形成在与电阻膜(7a)相对的一侧上的金属层(13)的第二电介质基板(12)。 当粘附到第二电介质基板(12)时,电阻膜(7a)具有由半导体电路芯片(6)的材料的介电常数确定的特性阻抗。 当其形成为与半导体电路芯片间隔开时,电阻膜具有等于空气的特性阻抗的薄层电阻。 第二电介质基板的厚度为期望频率的1/4波长。
