Abstract

The invention discloses a computer WIFI signal relay amplifier, and the amplifier comprises a signal input circuit, a first-stage amplification circuit, a second-stage amplification circuit, a third-stage amplification circuit, and a signal output circuit. The signal input circuit is connected with a signal output end of a WIFI receiving module, and is sequentially connected with the signal output circuit through the first first-stage amplification circuit, the second-stage amplification circuit and the third-stage amplification circuit. The signal output end of the signal output circuit is connected with a WIFI transmitting module. Compared with the prior art, the amplifier carries out three-stage amplification of a received WIFI signal, and the amplified signal is transmitted through a WIFI. The circuit can effectively enlarge the WIFI receiving range, avoids a plurality of routers, is convenient to use, and has popularization and application values.

Description

technical field [0001] The invention relates to a computer peripheral device, in particular to a computer WIFI signal relay amplifier. Background technique [0002] Wireless network refers to "wireless compatibility certification" in the category of wireless local area network, which is essentially a commercial certification and also a wireless networking technology. In the past, computers were connected through network cables, while Wi-Fi is connected through radio waves. The common one is a wireless router, so the effective range of radio wave coverage of this wireless router can be connected to the Internet by using a wireless fidelity connection. If the wireless router is connected to an ADSL line or other Internet access lines, it is also called hotspot. However, in the prior art, the WIFI signal of the router will be affected by buildings, resulting in a short transmission distance. Therefore, multiple routers need to be installed to make the signal stronger, which is...
