Low-power link promises range up to 0.5km
TLC2H and RLC2H
With a bitrate up to 5Kbit/s and a choice of 32 channels, the TLC2H transmitter and RLC2H receiver modules offer a low power, reliable datalink.
With a bitrate up to 5Kbit/s and a choice of 32 channels, the TLC2H transmitter and RLC2H receiver modules, from London-based manufacturer Radiometrix, offer a low power, reliable datalink.
They come in an industry-standard pinout and footprint, which makes these radio module pairs highly suited to applications where existing wideband modules have insufficient range, or where low cost multichannel operation is needed without compromising the RF performance.
Current consumption is kept to a minimum, with the transmitter running off just 34mA and the receiver needing a mere 18mA for operation The transmitter has an output power of 10mW (+10dBm), and the receiver sensitivity is -120dBm (for 12 dB SINAD).
These figures permit usable distances of over 500m to be achieved.
The RLCH2 receiver incorporates a peak sampling quasi-DC coupled design for data recovery, allowing serial data to be transmitted and received without the strict bit balancing requirement of a simple average and compare data slicer based receivers.
Standard operating frequencies supported span from 433.875 to 434.650MHz on a 100% duty cycle subband.
The frequency set up can be easily reprogrammed to any custom frequency within the 433 to 435MHz.
The standard version conforms to both EN300 220-3 and EN301 489-3 regulations.
The applications where it is most likely to be utilised are those where power is at a premium.
These include data loggers, handheld terminals, remote industrial monitoring/control, high-end security/fire alarms and heavy vehicle/machinery controls.
