Typical features include:

• PCB mounting, space saving SIL style

• 418 MHz SAW controlled wide band FM reception

• Selective double conversion superhet

• Sensitive typ. 0.5µV (-113 dBm) for 20 dB S/N

• High data rates, 5kbps and 10kbps

• Analogue and Digital data outputs

• Carrier detect output

• Fast enable time,< 3ms for duty cycle power save use

• Wide supply range, 4.0V to 9.0V

• Low current, 13 mA continuous, 130µA on power save (100:1)

• The SILRX radio receiver and the matching DTI (RA) approved transmitter (TXM-418-5) are self

contained, PCB mounting modules capable of transferring analogue or digital data up to a distance

of 200m.

The SILRX receiver module is particularly suitable for battery powered portable applications where it’s

low power requirements and small size are of advantage. It may also be used as a lower cost option to

the RXM-418-10 in fixed applications where the higher data rates and signal strength output of the

RXM-418-10 are not required.

Typical applications include:-

Site paging receivers

Paging car alarms

Line powered telephone auto diallers

Domestic and commercial security

Guard patrol/lone worker protection

Medical Alert/Nurse Call system

Mobile panic attack

Remote industrial process monitoring

Battery powered half duplex data networks

Data transfer through hazardous environments

Lighting control, Garage door openers

Fire alarms

Picture/antique protection alarms

Remote control, Access control

The SILRX-418-5 and SILRX-433-5 integrate a

complete FM superhet UHF radio receiver on a

small module. Together with the matching TXM-

418-5 or TXM-433-5 transmitter a one-way radio

data link can be achieved over a distance upto 200

metres on open ground
