HOPERF - universal RF modules for surprising prices

HOPERF modules enable to gain a wireless data transfer or remote control of devices simply and without excessive costs.
This is an archive article published 09/11/2014. Some information may no longer be up to date and in line with the current state. Please contact us in case of interest.

A company, which specializes over a quarter of century on a given segment usually has experience and production capacities to develop and produce quality components. This is also a case of company HOPERF Micro-electronics and moreover - thanks to high production capacities the prices of their products are very attractive. HOPERF produces RF chips themselves, as well as read-made RF modules usable for virtually any application requiring a wireless control or data transfer, for example: remote keyless entry (RKE), control, security systems, telemetry, voice and data communication, control of processes and many others.
HOPE RF modules offer besides a great price also a very high flexibility of usage. In contrast to many “fix-set” modules, RF modules HOPERF usually offer very wide possibilities to dynamically adjust many parameters, like for example: FSK/ OOK/ ASK modulation, possibility to work in a wide frequency range including free ISM bands 315, 433, 868 and 915MHz, while all main RF communication parameters are programmable.

In our stock can be found for example:

RFM65CW-433S2 and RFM65CW-868S2 - 433/868 MHz FSK receivers. RFM65CW offers a unique possibility to use narrow-band and also wide-band communication modes. RFM65CW is optimized for a low power consumption while maintaining high sensitivity.

RFM68CW-433S2 and RFM68CW-868S2 - 433/868 MHz FSK transmitters. It can be used without configuration from an MCU. However, in connection with MCU, it´s possible to change many parameters including output power, modulation format and a working channel.

RFM73-S - 2,4 GHz transceiver, including a high power +20dBm version RFM73P-S2.

RFM83C-433S1 - sophisticated 433 MHz ASK/OOK receiver including a version for low voltages RFM83CL-433S operating already from 2.1V

RFM85W-433D - 433 MHz ASK transmitter. Excellent features and simple usage. Specially designed for remote control, car-alarms etc. working on 433.92 MHz.

RFM12B-868S2P - multichannel 868 MHz FSK transceiver. RFM12B contains integrated functions of a digital data processing like: data filtering, clock recovery, data pattern recognition, integrated FIFO and TX data register. RFM12B enables to provide a clock for microcontroller.

Further information can be found in datasheets at particular types. In case of interest in any HOPERF module, please contact us at sales@soselectronic.com.

Advantages/ Features:
  • modern easily usable RF modules
  • wide possibilities of configuration including change of output power, frequency, modulation, ...
  • possibility to choose narrow-band/ wide-band mode
  • low power consumption/ high sensitivity
  • built-in temperature sensor and low voltage indicator
