Problems solved by technology

[0007] Also, the compactness of conventional temperature-compensated crystal oscillators is severely limited because of the space required to place the temperature-compensation components
For this consideration, this discrete TCXO cannot be successfully applied to mobile communication terminals

Embodiment Construction

[0022] The present invention will be further illustrated by examples in conjunction with the accompanying drawings.

[0023] figure 2 A side cross-sectional view of a temperature compensated crystal oscillator according to one embodiment of the present invention is shown.

[0024] As shown in the figure, the configuration of the temperature compensated crystal oscillator is a main board 201 , a ring plate 207 and a crystal package 203 laminated in sequence from the bottom to the top.

[0025] The main board 201 has piezoelectric devices, integrated circuits, capacitors, inductors and resistance elements to form a temperature compensation circuit. Area 207a is used to place components to form the temperature compensation circuit defined by the annular disk. The annular disk 207 is a frame structure with space configured therein, so that the annular disk 207 mounted on the motherboard not only supports the crystal package 203 placed on it, but also ensures that there is enough...

Abstract

A temperature compensated crystal oscillator, which is manufactured by placing a ring-shaped board on a main board to accommodate compensating components on the main board, and placing a crystal package on the ring-shaped board, is disclosed. A component mounting area on the main board is reduced, thereby reducing a product size. At least one conductive pad may be attached to the ring-shaped board to connect the crystal package to a certain circuit on the main board. The conductive pad may be provided at each of four corners of the ring-shaped board in the case of a rectangular ring-shaped board. The present invention also provides a method of manufacturing the temperature compensated crystal oscillator.

Description

field of invention [0001] The present invention relates to a temperature-compensated crystal oscillator and its manufacturing method, in particular to a temperature-compensated crystal oscillator and its manufacturing method. The inner space of the ring disc to obtain a compact structure of the product. Background technique [0002] A crystal oscillator using a quartz oscillator is a main element for generating an oscillation frequency that controls signals transmitted and received between mobile communication terminals, and is more advanced than other oscillators in frequency stability. However, the quartz oscillator has a disadvantage that its oscillation frequency varies according to the ambient temperature. In order to overcome this disadvantage, some additional components must be added to the crystal oscillator to compensate for frequency variations due to this temperature characteristic of the crystal oscillator. Such a crystal oscillator is called a temperature comp...
