Abstract

The invention relates to a small strip-shaped linear power amplification module which comprises a substrate (1), a power transistor (2), a printing board A (3), a printing board B (4), a printing board C (5), a printing board D (6), a feed circuit A and a feed circuit B. The printing board C (5) and the printing board A (3) form an input matching circuit. The printing board D (6) and the printing board B (4) form an output matching circuit. The input matching circuit and the output matching circuit are connected with the power transistor (2). The feed circuit A and the feed circuit B are connected with the input matching circuit and the output matching circuit respectively. A gold-covered layer (7) and a copper-covered layer (8) are arranged on the side face and the combined face of each printing board respectively. Common grounding of a strip-shaped linear circuit in the module is achieved through copper-covered structures of the combined faces of the printing boards and gold-covered structures of the side faces of the printing boards, the number of procedures is reduced, a better common grounding effect is further provided, and large-power high-frequency work of the power amplification module is facilitated.

Description

technical field [0001] The invention relates to the technical field of power amplification modules, in particular to a miniaturized stripline power amplification module. Background technique [0002] Power amplifier modules not only play an important role in modern wireless communications, but also occupy an important position in military and civilian equipment. With the continuous development of semiconductor technology, the current power amplifier module is mainly realized by microstrip line. In the engineering manufacturing process, the stripline circuit is usually covered with copper skin to ensure the commonality between the upper printed board and the lower printed board. land. However, the process steps of copper cladding are very cumbersome, the manufacturing cost is high, the operation takes a long time, it is easy to be damaged, it is not conducive to debugging, and it is not easy to realize under high frequency. Contents of the invention [0003] The object of...
