Comparison of several amplifier wireless module schemes

The transmit amplifier power of general wireless modules on the market can be divided into large, medium and small power. According to the different transmission power, its use is also different. In order to facilitate users to make a reasonable choice, here we compare the common high-power amplifier wireless module schemes to facilitate customers to make appropriate choices when using the wireless module.

Common chip solutions for wireless modules include:

CC1312/CC1311

CC1310

CC1120

SI4463

SX1278/SX1276

ADF7023

ASK

CC2500, etc.

Characteristics of each scheme
