TRM-xxx-DP1203
Data Guide
General Description
(Preliminary)
The TRM-xxx-DP1203 is a complete Radio
Transceiver Module operating in the 433, 868
and 915 MHz license free ISM (Industrial
Scientific and edical) frequency bands.
The TRM-xxx-DP1203 offers the unique
Figure 1: TRM-xxx-DP1203 Module
advantage of high data rate communication
up to 152.3kbps. The radio module is suitable for applications seeking to
satisfy the European (ETSI EN300-220-1 and EN301 439-3) or the North
American (FCC part 15.247 and 15.249) regulatory standards.
The TRM-xxx-DP1203 modules can be used in any environment where
wireless remote connection is an advantage. The TRM-xxx-DP1203
modules are perfect for complex wireless networks involving high speed
data rate applications.

Warning:
Linx radio frequency (“RF”) products may be
used to control machinery or devices remotely, including machinery
or devices that can cause death, bodily injuries, and/or property
damage if improperly or inadvertently triggered, particularly in industrial
settings or other applications implicating life-safety concerns. No
Linx Technologies product is intended for use in any application without
redundancies where the safety of life or property is at risk.
The customers and users of devices and machinery controlled with
RF products must understand and must use all appropriate safety
procedures in connection with the devices, including without limitation,
using appropriate safety procedures to prevent inadvertent triggering by
the user of the device and using appropriate security codes to prevent
triggering of the remote controlled machine or device by users of other
remote controllers.
All RF products are susceptible to RF interface that can prevent
communication.
Do not use any Linx product over the limits in this data guide.
Excessive voltage or extended operation at the maximum voltage could
cause product failure. Exceeding the reflow temperature profile could
cause product failure which is not immediately evident.
Do not make any physical or electrical modifications to any Linx
product.
This will void the warranty and regulatory and UL certifications
and may cause product failure which is not immediately evident.
!
Warning:
ESD sensitive device. Precautions should be taken
when handling the device in order to prevent permanent damage.

Detailed Electrical Specifications
Figure 3 gives the specifications of the TRM-xxx-DP1203 modules under
the following conditions:
Supply voltage VDD = 3.3V, temperature = 25°C, frequency deviation
Δf
= 5kHz, Bit-rate = 4.8kbps, base-band filter bandwidth BWSSB = 10kHz,
carrier frequency fc = 434MHz for the TRM-433-DP1203, fc = 869MHz
for the TRM-868-DP1203 and fc = 915MHz for the TRM-915-DP1203,
bit error rate BER = 0.1% (measured at the output of the bit synchronizer),
antenna output matched at 50Ω.
