The RFM integrated short-range radios are attractive to original equipment manufacturers (OEMs) that design their own RF circuit. All RFM integrated short-range products are optimized for RF performance and feature a high-level of integration all in a small form factor. The benefits to designers are low-cost, efficient design cycles, and fast time-to-market. They are highly cost-effective in high volume applications.

Frequency:
In North or South America, if the application is for remote control choose 303 MHz or 433 MHz frequencies. If the application is for transmitting data choose 900 MHz.
In Europe, choose 433 MHz or 868 MHz for all applications.
In Asia and Pan Pacific, choose from any offered frequency. The RF power output is software programmable to meet the rules / regulations of a wide range of countries.
Data rate and range: Choose the data rate and distance / line-of-sight range over which the remote control is to be activated or over which the data is to be transmitted.
RF Power and RX / TX Current: Is long battery life or transmission distance primarily important? The lower the power / current the longer the battery life. The longer the transmission range the higher the power / current required to transmit over extended ranges.

Also, is the application to be powered by main or by battery? If battery, then obtaining the lowest power / current is critical.

Modulation and Technology: Does the application require noise immunity or resistance to fading? Modulation enables transmission across a single channel (OOK/ASK) or multi-channel (FSK) to affect desired level of noise immunity. FSK and FHSS offers highest immunity to interference.
Features: All SAW-based and RFIC short-range radios include a sleep mode feature to reduce power consumption.

Duty Cycle: Is programmable duty-cycle important (helps to regulate RF power output)? RFM 3rd generation SAW-based and RFIC short-range radios include a software programmable duty-cycle feature.

Clock Recovery: Is clock recovery needed within the RF device? RFM 3rd generation SAW-based and RFIC shortrange radios have built-in clock recovery so that the microprocessor does not have to perform that function to minimize the processing overhead on the microprocessor. RFM 2nd generation short-range radios do not feature built-in clock recovery as they interface to encoders/decoders with built-in clock recovery.

Start Symbol: RFM’s third generation SAW-based and RFIC short-range radios include a transmission start symbol option. The start symbol allows the receiver to automatically detect the start of a message, unloading this function from the host microprocessor. If automatic message detection by the radio is not mandatory, a second generation SAW-based radio can be used to achieve lowest receiver current.

Interface to microprocessor: Does your microprocessor have limited I/O? If so choose a shortrange radio with serial (SPI) interface. Choose a short-range radio with digital interface if your microprocessor requires digital I/O.
Package: SAW-Based Short-range radios are encased in a rugged, self-shielding, metal ceramic, hybrid package. RFIC Short-range radios are encased in smaller plastic packages.
