The DR4101 transmitter module is ideal for short-range wireless data applications where robust operation, small size and low power consumption are required. The DR4101 utilizes Murata's TX5001 amplifier-sequenced 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 DR4101 includes the TX5001 plus all configuration components in a ready-to-use PCB assembly, excellent for prototyping and intermediate volume production runs.
