TX3B-xxx.xx-64
869MHz Wide Band FM Transmitter
The TX3B radio transmitter module is
an enhanced high power replacement
for the European version TX3A-869-64
transmitter
Two frequency variants are available
in the European unlicensed band, one
with 5mW RF power with no duty cycle
restriction other with 8mW RF power
with 1% duty cycle restriction.

! RF power output
+9dBm (8mW) on 868.30MHz
+7dBm (5mW) on 869.85MHz
! Data rates up to 64kbps
! Crystal controlled PLL FM transmit circuitry

Available for operation in the 868-870MHz band in Europe, it combine full screening with internal
filtering to ensure EMC compliance by minimising spurious radiation and susceptibility. The TX3B and
matching RX3A will suit one-to-one and multi-node wireless links in such applications as car and
building security, EPOS and inventory tracking, remote industrial process monitoring and data
networks. Because of their small size and low power requirements, both modules are ideal for use in
portable, battery-powered applications such as hand-held terminals.
Applications
! Tracing and asset tracking systems
! Handheld terminals
! Meter reading systems
! Industrial telemetry and telecommand
! Data loggers
! In-building environmental monitoring and control
! Security and fire alarms
! Vehicle data up/download
