DR4103

Preliminary DR4103 Designed for Short-Range Wireless Data Communications Supports up to 115.2 kbps Encoded Data Transmissions 3 V, Low Current Operation plus Sleep Mode Ready to Use OEM Module The DR4103 transmitter module is ideal for short-range wireless data applications where robust operation, small size and low power consumption are required. The DR4103 utilizes RFM’s TX5003 amplifiersequenced hybrid (ASH) architecture to achieve this unique blend of characteristics. The transmitter includes provisions for on-off keyed (OOK) and ASK modulation. The transmitter employs SAW filtering to suppress output harmonics, facilitating compliance with FCC 15.249 and similar regulations. The DR4103 includes the TX5003 plus all configuration components in a ready-to-use PCB assembly, excellent for prototyping and intermediate volume production runs. 303.825 MHz Transmitter Module Absolute Maximum Ratings Rating Power Supply and All Input/Output Pins Non-Operating Case Temperature Soldering Temperature (10 seconds) Value -0.3 to +4.0 -50 to +100 230 Units V °C °C Electrical Characteristics, 2.4 kbps On-Off Keyed Characteristic Operating Frequency Data Rate OOK ASK Transmitter Performance (OOK @ 2.4 kbps) Peak Input Current, 3 Vdc Supply Peak Output Power Turn On/Turn Off Time Power Supply Voltage Range Operating Ambient Temperature ITP PO tON/tOFF VCC TA 2.7 -20 0.75 12/6 3.5 +65 12 mA mW µs Vdc °C Sym fO Notes Minimum 303.625 Typical Maximum 304.025 19.2 115.2 Units MHz ...
