TX2H-4xx-64
UHF High Power FM Transmitter
The TX2H is a 433/434MHz single-channel FM
transmitter module with a power output of
25mW nominal. It is a 100% pin-compatible
drop-in replacement for the Radiometrix TX2
and can be used to replace the TX2 in
applications where greater radiated power is
desired (for example when space limitations
dictate the use of small and inefficient antennas,
or in countries where the extra power is
permitted). The module will handle raw data
rates up to 64kb/s. The TX2H transmitter can be
used with either RX2G or RX2A receivers.
Features
Figure 1: TX2H-433-64-5V & RX2A-433-64
Standard frequencies: 433.92MHz and 434.42MHz
Hi power drop in replacement for TX2
Data rates up to 64kbps
Usable range over 500m
Fully screened
Low power requirements
Conforms to European EN 301 489-3 and ETSI EN 300 220-3 (for ERP 10mW)
Conforms to Australian/New Zealand AS/NZS 4268:2003
Instead of the SAW-based technology of the TX2, the TX2H uses a PLL circuit locked to a crystal for
better frequency stability over a wider temperature range (-40C to +85C), at the expense of slightly
slower power-up.
The TX2H is available as standard on frequencies of 433.92MHz and 434.42MHz at 25mW power output,
in either 3V(3.3V) or 5V versions. Custom frequencies may be available to order (consult factory). The
module is designed to meet all applicable EMC and type approval requirements.
The module can be made available if required in an extra-high-power version (TX2EH), in the same
footprint and pinout but giving 90-100mW nominal output power at 5V supply with a current
consumption of less than 45mA (DC to RF conversion efficiency better than 45%).
Applications
Handheld terminals
Data loggers
Industrial telemetry and telecommand
In-building environmental monitoring and control
High-end security and fire alarms
Vehicle data up / download
