UWB Module SDWM1000 Circuit Diagram and PCB - Price: $300 USD
This is our later mass production module. The module uses a PCB antenna and uses pin headers to connect to the anchor chassis. Can be directly adapted to two models of indoor anchors, A1102P and A1106P.
This module has basically the same circuit as the original DWM1000 and has no extra functions. Please note that LNA and PA are not added .
We have tested that when using 850K rate, the longest communication distance is about 200 meters to 300 meters .
Someone may wonder why the module circuit is more expensive than the anchor backboard circuit?
Because of the difficulty! Hardware engineers know that in most cases, digital circuits are simpler than analog circuits.
Although we have modified the chassis of the single network port anchor dozens of times, the changes are all in details. It cannot be said to be worthless, but it is not strictly necessary.
In the early days, in order to reduce the difficulty of research and development, we always used the original UWB module. As the product matured and we hoped to reduce production costs, we decided to develop our own UWB module. The difficulty in developing UWB modules mainly lies in wiring. The wiring of the RF circuit is not just about impedance matching. This has always been a technical job, which requires not only theoretical support but also empirical support. We tried it many times before we got a satisfactory result. You can think about it, how long does it take a qualified engineer who is proficient in RF wiring to figure this thing out? How much salary are you going to pay him? For this price, it's just free of charge.
