Description
These miniature RF modules provide a cost effective high performance FM Radio data link, at,
433.92MHz. The modules uses no adjustable components ensuring very reliable operation.
This transmitter and receiver pair enables the simple implementation of a data link at distances up
to 75 metres in-building and 250 metres open ground.
The modules have been approved for operation with Europe and USA within FCC part15.
These modules will suit one-to-one and multi-node wireless links in applications including car and
building security, EPOS and inventory tracking, remote industrial process monitoring and computer
networking. Because of their small size and low power requirements both modules are ideal for use
in portable, battery-powered applications such as hand-held terminals.

RSSI Output
The RSSI provides a DC Voltage proportional to the peak value of the receive data signal. This output can be used as an indicator for the received signal strength to use in wake-up circuits etc.
An used to provide the timing for the RSSI signal. The modules have a 10nF capacitor internally
connected tRC circuit is normally o GND, therefore a pull down resistor (to GND) connected to
the RSSI pin may be used to generate a simple RC network time constant for the RSSI signal output.
Please note that the maximum output current is typically 950µA, the discharge current is lower
than 2µA

Prototyping Hints
It is essential when building any Low Power Radio System that you have a ‘clean’ DC power
source. Typically the ripple voltage should be less than 10mV Peak to Peak. Normally a 470uF decoupling capacitor is sufficient de-coupling for an AC derived DC power source. Small capacitors
of 10-100nF can also be used across the power supply to filter high frequency noise.
Never place a Transmitter or Receiver directly into Vero-Board or any similar prototyping board.
This will severely restrict the range. Rather, use small lengths of wire from the prototyping
board to the pins of the Transmitter or Receiver.
A useful antenna, for testing purposes, for both the Transmitter and Receiver on 433MHz is to
use a piece of wire 17.3cm long (23.8cm at 315MHz) soldered directly to the antenna pin.
Data should be encoded before it is transmitted over a wireless link to ensure reliability and reduce the effect of interference and cross talk. A range of encoders IC’s are available from RF Solutions, please refer to the RF Solutions website for further information.
