... Usable range to 10km+ Screened construction Available for licence-exempt operation in the UK 173MHz bands, the TX1 & RX1 modules combine effective screening with internal filtering to minimise spurious radiation and susceptibility thereby ensuring EMC compliance. They are particularly suitable for one-to-one and multi-node wireless links where longer ranges are required at low to moderate data rates ...

... The RX1 module is a single conversion NBFM superhet receiver capable of handling data rates 10kbps. It will operate from a supply of 2.7V to 12V and draws 12mA when receiving. A signal strength (RSSI) output with greater than 80dB of range is provided. The SIL style RX1 measures 48 x 17.5 x 5.5 mm excluding the pins. ...

... Digital output from internal data slicer (squared version of the signal on pin 8). It may be used to drive external decoders. The data is true data, i.e. as fed to the transmitter. Output is “open-collector” format with internal 10k pullup to Vcc (pin 7). Radiometrix Ltd., TX1 & RX1 Data Sheet Regulated Rx supply FM ...

... Lower limit can be extended required, by means of external circuitry. 5. For received signal with 3kHz FM deviation. 6. Typically 4ms for signal at channel centre, maximum 12ms at 4kHz RF offset. 7. For 50:50 mark to space ratio (i.e. squarewave). 8. Average over 50ms period at maximum bit rate.

... Note, however, that for supply voltages lower than 2.85V the regulator is effectively inoperative and supply ripple rejection is considerably reduced. Under these conditions the ripple/noise on the RX1 supply rail should be below 20mV ...

... Keep all tracking around the attenuator network as short as possible, particularly ground paths, and use matched 50 microstrip lines for input and output connections (track width of 2.5mm if using 1.6mm thick FR4 PCB). Radiometrix Ltd., TX1 & RX1 Data Sheet Vcc Series resistor ...

... Note: The figure for 1.2kbps assumes that the receiver bandwidth has been suitably reduced by utilising an outboard audio filter/data slicer or similar arrangement. If the RX1 is used “as is” the range will be similar to that for 10kb/s. Radiometrix Ltd., TX1 & RX1 Data Sheet RF Input Level (dBm) Fig ...

... TX1 introduces some 2 necessary by predistortion of the analogue waveform. At the other end of the link the RX1 AF output is used to drive an external decoder directly. Although the modulation bandwidth of the TX1 extends down to DC, as does the AF output of the RX1 not advisable to use data containing a DC component ...

... Loop. A loop of PCB track having an inside area as large as possible (minimum about 5cm matched with 2 capacitors. Loops are relatively inefficient but have good immunity to proximity detuning, so may be preferred in shorter range applications where high component packing density is necessary.

... Integral antenna summary: Ultimate performance Ease of design set-up Size Immunity to proximity effects Tamper-proof integral antenna Where the RX1 is used in alarm applications it may sometimes be necessary to provide a warning if any attempt is made to remove or disable its antenna. A typical solution to this problem is as follows: 1/4 wave hairpin loop antenna 1n R1 Fig ...
