TX2H / TX2EH

433MHz High Power Transmitter

The TX2H is a 433.92MHz 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 TX2H transmitter can be used with RX2 or RX2A receivers.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 module can be made available if required in an extra-high-power version (TX2EH), in the same footprint and pinout but giving 100mW nominal output power at 5V supply with a current consumption of less than 45mA (DC to RF conversion efficiency better than 45%).
