W E N 05 October 2009 Radiometrix Hartcran House, 231 Kenton Lane, Harrow, HA3 8RP, England Tel: +44 (0) 20 8909 9595, Fax: +44 (0) 20 8909 2233 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).
