DR4103 303.825 MHz Transmitter Module

The TX IN pin is connected to the transmitter TXMOD pin through a 4.7 K resistor on the circuit board. Additional series resistance will often be required between the modulation source and the TX IN pin, depending on the desired output power and peak modulation voltage (3.3 K typical for a peak mod.

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.
