Description
These miniature RF modules provide a cost effective high performance FM Radio data link, at either 315,
433.92 or 868MHz. Manufactured using laser trimmed processes on thick film ceramic substrates, the hybrid
modules exhibit extremely stable electronic characteristics over an industrial temperature range. The hybrid
technology 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.
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, batterypowered 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 RC circuit is normally used to provide the timing for the RSSI signal. The modules have a 10nF capacitor
internally connected to 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

Notes
1. Time from PD pin going high to stable data. (RRFQ1 only)
2. Time from Power ON to stable data.
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.
