High Power 500mW
Narrow-Band RF Module Targets
Long Range Applications
Radiocrafts AS, a leading RF module supplier, now
expands their product line with a high power narrow-band
RF module for the European market.
RC1280HP, offering up to 500 mW output power for
increased range, is based on the RC1280 RF Transceiver
Module for FSK operation with embedded protocol. When
used with quarter-wave antennas a line-of-sight range of
5-6 km can be achieved. The new RC1280HP module uses the
same protocol and channels as the RC1280. Interoperation
between RC1280 and RC1280HP is therefore possible in a
network with both long- and shorter range modules.
The module is pre-certified and CE marked for
operation under the European radio regulations for
license-free use in the 868 MHz band, operating in 3
channels in the sub-band at 869.400 – 869.650 MHz. Up to
10% duty-cycle (transmission ratio) is allowed in this
band. The new high power module can also be used outside
this sub-band if the power amplifier is disabled,
reducing the output power to less than 10 mW.
The RC1280HP module yields a high performance, low
power, two-way radio solution with an embedded RC232™
protocol supporting point-to-multipoint networks. Based
on narrow-band technology, the module offers increased
performance in terms of sensitivity, selectivity, data
integrity and range. The module contains a multi-channel
transceiver with a receiver sensitivity of -108 dBm at
4.8 kbit/s. With 30 dB adjacent channel rejection, 40 dB
alternate channel selectivity and outstanding blocking
properties, the module offers exceptional performance
even in a crowded and noisy environment.
The new module measure only 19.5 x 60.5 x 6.0 mm, and
comes in a DIL-style package with 2.00 mm pin pitch made
for low profile board-to-board connection.
Data buffering, addressing and error check are all
handled by the embedded RC232™ protocol. A standard UART
serial bus is the interface to the host for both data
communication and configuration.
Typical applications include long range telemetry and
remote control, automatic meter reading (AMR), fleet and
asset management, home-, building- and industrial-
automation, wireless security and alarm systems.
The new module's major benefit is the extended
communication range in the 868 MHz band. More robust and
reliable links are achieved, still operating within the
license-free band. The high power radio combined with
narrow-band technology meets the stringent requirements
for license-free operation in the 868 MHz band. OEM
manufacturers without RF design knowledge can now easily
add a high performance long range wireless link to their
products, and significantly reduce time-to-market,
development and certification cost.
