Title:
OSCILLATION CIRCUIT DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/094730
Kind Code:
A1
Abstract:
Provided is an oscillation circuit device making it possible to implement stable oscillation properties without increasing costs. An oscillation circuit device (1) has an amplifier circuit (22) configured on a main board (3), and a coupling circuit (23), feedback circuit (25), and power output port (24) configured in a semiconductor layer on the main board (3). The coupling circuit (23) and the feedback circuit (25) constitute a microstrip line (8) that operates with a grounded housing (2) being set to a reference potential. The grounded housing (2) has a protrusion (12) extending out from an inner surface thereof toward the microstrip line (8), and an air layer (13) is formed between the protrusion (12) and the microstrip line (8).
