Title:
HIGH FREQUENCY LOW-NOISE AMPLIFIER
Document Type and Number:
Japanese Patent JP2017046297
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a high frequency low-noise amplifier, capable of suppressing unwanted oscillation while approaching an impedance to minimize the noise figure and an impedance to maximize the gain.SOLUTION: A high frequency low-noise amplifier includes a circuit board, a first and a second bonding wires, and a field effect transistor. The circuit board includes a ground conductor on its reverse surface, and a first and a second microstrip lines. One-end parts of the microstrip lines are connected to the ground conductor, and the microstrip lines provide inductance. The other-end part of the first microstrip line and a source electrode are connected with a first bonding wire. The other-end part of the second microstrip line and a source electrode are connected with a second bonding wire. A distance between the one-end part and the other-end part of the microstrip line is different from a distance between the one-end part and the other-end part of the second microstrip line.SELECTED DRAWING: Figure 1
