High power RF module designed for ZigBee


Oslo, Norway — (METERING.COM) — January 24, 2008 – Radiocrafts AS, a provider of compact RF modules, has expanded its product line with a compact high power RF module design for ZigBee™ operating at 2.45 GHz. The new module deliver up to 18 dBm output power, and gives an increased communication range of up to ten times compared to standard low output power modules.

The new RC2201HP is compliant with IEEE 802.15.4 and is designed for ZigBee Full Function Device (FFD) and Reduced Function Device (RFD) operation, or other protocol stacks using star or mesh topologies.

The complete shielded module is only 16.5 x 35.6 x 3.5 mm, optionally available with integrated antenna. An integrated microcontroller makes it possible to embed the complete application in this tiny module. The output power can be adjusted to comply with EU regulations for CE marking, as well as FCC and ARIB approvals.

Some of the features for the Radiocrafts RC2201HP module are:

  • Up to 18 dBm output power, giving 10 times range increase
  • Receiver sensitivity of -94 dBm at 250 kbit/s
  • 16 channels at 2.45 GHz compliant with IEEE 802.15.4
  • Small size: 16.5 x 35.6 x 3.5 mm
  • Shielded module with integrated antenna
  • 128 kB flash memory, 8 kB RAM
  • 32 digital and analogue I/Os, 8 channel 10 bit ADC
  • UART and SPI interfaces
  • Suitable for full or reduced function ZigBee stack.

The module is based on DSSS (Direct Sequence Spread Spectrum) technology and offers exceptional range and performance even in crowded and noisy environments. Low power modes for increased battery life are available.

“With this new module, line-of-sight ranges of 1500 m can be achieved with external antenna, and 800 m with the integrated antenna”, says Peder Martin Evjen, Managing Director.

Typical applications include home, building and industrial automation, wireless security and alarm systems, automatic meter reading, remote control and telemetry, fleet and asset management. Operation at the 2.45 GHz license free band enables world-wide usage.
