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 RX2 or RX2A receivers.

Features

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%).
