The DR4100 transmitter module is ideal for short-range wireless data applications where robust operation, small size and low power consumption are required. The DR4100 utilizes RFM’s TX5000 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 ETSI 300 220 and similar regulations. The DR4100 includes the TX5000 plus all configuration components in a ready-to-use PCB assembly, excellent for prototyping and intermediate volume production runs.
