Title:
HIGH-FREQUENCY CIRCUIT BOARD
Document Type and Number:
Japanese Patent JP2012114696
Kind Code:
A
Abstract:
To provide a high-frequency circuit board capable of suppressing passage loss of a high-frequency transmission line, such as a microstrip line for transmitting a high-frequency signal, and achieving high productivity, as well as low noise from a low-noise amplifier, high saturation power of an amplifier for transmission and low phase noise from a voltage variable oscillator.
The high-frequency circuit board includes: a transmission line formed from a metal conductor on a surface of an insulator substrate and a solder layer formed from reflow solder on a surface of a transmission line.
