315 mhz or 433.92 mhz rf Superheterodyne receiver module AG-RXB31

AG-RXB31 is VHF/UHF high frequency wireless data transmission of high-quality superheterodyne receiver module. it used in

Europe were the most advanced ultra-high frequency, low noise RF integrated circuits, there are anti-static protection and high 

reliability. it very easy pass the FCC/CE certification.

It is rolling code remote control,door control system, garage door as well as long distance transmission of choice.

it very stable and reliable,high sensitivity is widely used in a variety of interference,harsh environment applications.

Key Features

1). Sensitivity up to -115dBm,receiving distance is more than twice the normal receiver board

2). Reasonable receiver bandwidth, with strong co-channel rejection capability,strong anti-interference ability to adapt to various 

environments

3). Good distribution of radiation suppression,and easy through the FCC/CE

4). Good shielding,small influence of various installation environment performance of the module,and good consistency

5). Good local oscillator radiation suppression,can work with multiple modules (single income) and will not interfere with each

 other,does not affect the receiving distance

6). Using SAW LO,stable performance,wide temperature range

7). SCM direct interface,easy to implement

8). Antenna module receivers a great effect,then the best 1/4 wavelength single copper wire

9). Antenna position also affected the reception of the module can be soldered directly to the antenna ANT interface can also be

 connected to the system via the ANT pin and then to the antenna,install the antenna stretched as far as possible,away from the 

shield,high pressure,and sources of interference

Applications

1). Garage door wireless control system

2). Electric windows,barrier etc.

3). Industrial control, communications security etc. Fields

4). Low baud rate for data transmission

5). GSM/GPS car system

Test Instrument

Oscilloscope, Function Generator, Power and test tool (tool with 5V power supply).

Test step

1). Use shielding wire connection Oscilloscope, Function Generator and Test tool.

2). Power on the device set oscilloscope and function generator parameters (frequency and sensitivity -105dBm).

3). Receiver board voltage signal in accordance with the above tolling pin inserted oscilloscope will appear above a standard sine

wave, so for qualified products. If the wave shape shaking and no wave is defective products.

4). All the above steps to complete at the shielded room (outside have interference of radio waves affect the test standard).
