DATA SHEET
Receiver Module : RWS-A916 (916.5MHz )
-Designed for Short-Range Wireless Control and Data Communications -Supports RF Data Transmission Rates Up to 200 kbps -2.4 V, Low Current Operation plus Sleep Mode -Stable, Easy to Use, Low External Parts Count The RWS-A916 MODULE receiver is ideal for short-range wireless control and data applications where robust operation, small size, low power consumption and low cost are required. The RWS-A916 MODULE All critical RF functions are contained in the MODULE, simplifying and speeding design-in. The RWS-A916 is sensitive and stable. A wide dynamic range log detector, in combination with digital RSSI and a compound data slicer, provide robust performance in the presence of on-channel interference or noise. FCC 15.249 and similar regulations. CAUTION: Electrostatic Sensitive Device. Observe precautions when handling. Notes: 1. OOK BER measured with no DS1 threshold (DS2 disabled), and data encoded for DC-balance with a run length limited to 4 bit periods. 2. ASK BER measured with a 25 mV DS1 threshold, DS2 threshold 6 dB below peak, and data encoded for DC-balance with a run length limited to 4 bit periods. 3. Sleep to receive recovery time is for the sleep period and signal level indicated, -40 to 60 C.Recovery time will increase at higher temperatures, for longer sleep intervals and lower signal levels. 9600BSP to change 100KBPS cut capacitance a.b.c Absolute Maximum Rating Rating Power Supply and All Input/Output Pins Non-Operating Case Temperature Soldering Temperature (10 seconds) Value -0.3 to +12.0 -20 to +85 230 Units V C C
