• Which FSK Transceiver Module is better, Si4438 RF module or Si4463 RF module?

  Both Si4438 and Si4463 are RF chips launched by Silicon Labs. The RF modules developed from these two chips have their own advantages and strengths. The performance of Si4463 RF module is far better than the Si4438 RF module. If cost is not a problem, the Si4463 RF module is definitely the best choice.

• Is the Higher Antenna Gain Always the Better?

  We often get customer's inquiry and ask if we can provide a high gain antenna, someone even says the higher gain the better. But is that true? Is really higher gain antenna result a better effect? In fact, this view is incorrect. Simply to increase the gain, although the coverage distance is greater, the coverage will become narrower.
