SILRX-UHF
UHF Radio Telemetry Receiver Module
UK version:
Euro version:
SILRX-418-5 / SILRX-418-10
SILRX-433-5 / SILRX-433-10
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

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
Guard patrol/lone worker protection
Mobile panic attack
Domestic and commercial security
Medical Alert/Nurse Call system
Remote industrial process monitoring
Data transfer through hazardous environments
Fire alarms
Battery powered half duplex data networks
Lighting control, Garage door openers
Picture/antique protection alarms
Remote control, Access control
