EW N 08 January 2008 Radiometrix Hartcran House, 231 Kenton Lane, Harrow, HA3 8RP, England Tel: +44 (0) 20 8909 9595, Fax: +44 (0) 20 8909 2233 TX3H-869.50-10 UHF Wide Band FM 450mW Transmitter The TX3H-869.5-10 is an 869.5MHz FM transmitter module with a power output of 450mW nominal. It is a 100% pin-compatible drop-in replacement for the Radiometrix TX1H-151.30010and can be used in applications where greater radiated power is desired (for example when space limitations dictate the use of small and inefficient antennas, or for applications where the extra power is permitted). The module will handle raw data rates up to 10kbps. Figure 1: TX3H-869.50-10 & RX3A-869.50-10 Features • • • • • Standard frequency: 869.50MHz band Data rates up to 16kbps Usable range over 3km Fully screened Low power requirements The TX3H operates on European 869.40 – 869.65MHz sub-band allocation for 500mW and is designed to meet EN300 200-3 (radio) and EN301 489-3 (EMC) requirements. Custom frequencies may be available to order. Technical Summary • • • • • • Transmit power: 450mW (26.5dBm, ±1dB) Operating frequency: 869.50MHz Supply: 5V (regulated) Current consumption: 310mA (typical) Data bit rate: 16kbps max.
