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. DS069-8 Aug 07 ©2007 Reg.

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 DS069-8 Aug 07 ©2007 Reg.

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. DS069-8 Aug 07 ©2007 Reg.
