Description

This RF wireless high-frequency receiving module has a sensitivity of up to -103dBm and an ultra-small size. It can be used for remote controls. It is an ideal choice for GSM/GPS vehicle-mounted systems and industrial control, and can also be used in systems with high requirements in complex environments. It can replace the infrared receiver, and there is no dead angle for receiving. It is easy to design and add to the general remote control.

Features

1. The sensitivity is as high as -103dbm, and the receiving distance is more than three times that of ordinary receiving boards;
2. It has reasonable receiving bandwidth, strong same-frequency suppression ability, strong anti-interference ability, and is suitable for use in various environments.
3. Good collection and distribution radiation suppression ability, easy to pass various testing standards.
4. Suitable for 250-450MHz, easy to adjust each frequency point, and short delivery cycle.
5. Direct interface with single-chip microcomputer, easy to implement (transmission rate up to 20kbps) .
6. Strengthen the anti-interference ability of mobile phones/improve the decoding waveform.
