RF125 is a low-power, long-distance, wireless air wake-up and data transceiver module launched by our company. It is mainly used in RKE keyless access control, campus access control, etc.
Last time I introduced the typical application of RF125. Today, the editor of NiceRF will analyze whether RF125 is compatible with AS3933 on the market and what advantages it has in terms of performance.
Please see the comparison of the two chips in the table below:
1. Three-channel low-power ASK receiver;
2. Carrier frequency range: 15KHz-150KHz;

1. Real-time positioning system;
2. Operator identification;
3. Access control and wireless sensors.
Compatibility：Both RF125 and AS3933 are 3-channel ASK receivers, which can generate a wake-up signal when a data signal with a carrier frequency of 125 KHz is detected. It can be used to wake up active tags in RTLS, PKE and other similar tracking and access control systems. RF125 is perfectly compatible with AS3933 without changing the software and hardware.
RF125 has an automatic antenna tuning function, which has several more registers than the basic function of AS3933, which greatly increases the space for users and has high flexibility.
RF125 can adjust the receiving sensitivity according to different application scenarios, and realize longer-distance communication while ensuring the receiving sensitivity. At the same time, the automatic tuning feature ensures that the chip is perfectly matched with the expected carrier frequency, which greatly simplifies the antenna tuner.
According to different application scenarios, RF125 can achieve direction positioning and position recognition by switching the Manchester recognition mode.
In terms of performance and price, RF125 has dumped AS3933 a few streets. Become the customer's first choice for low frequency wake-up devices.
The above is the perfect compatibility and performance advantages of the low-frequency wake-up chip RF125 used by our company's RF125 and AS3933. It can be seen that our new product RF125 has more advantages in campus access control cards, PKE keyless access control and other applications.
