**-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.
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-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
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
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.
