A linear amplifier is an electronic circuit whose output is proportional to its input, but capable of delivering more power into a load. Linearity refers to the ability of the amplifier to produce signals that are accurate copies of the input.

Sometimes, our mobile phone has poor signal reception in our house, the reasons are as below: Distance from the nearest cell tower. The farther away you are from a cell tower, the weaker the signal will be. If you live in a rural area or in a valley, you may be further away from cell towers, which can cause poor reception. Building materials. Some building materials, such as concrete, brick, and metal, can block cell signals. If your home is made of these materials, it can make it difficult to get a good signal.

The type of cell phone signal you need: There are signal boosters for 3G, 4G, and 5G cell phone signals. Make sure to choose a booster that supports the type of signal you need.

here are some factors to consider when selecting a suitable antenna for a cell phone signal booster : The type of cell phone signal booster you have .  The size of the area you need to cover . The location of the cell phone signal booster.  The budget .

Increase in penetration of 5G networks. 5G networks offer much faster speeds than 4G networks, which will require repeaters to be able to amplify these signals.
