Telemetry Transmitters (ETT Series)

The ETT Telemetry Transmitter series is Emhiser’s core line of analog FM airborne telemetry transmitters, spanning L-band and S-band frequency ranges such as 1435-1540 MHz (D1) and 1710-1850 MHz (D2), in single-frequency and channelized configurations. Catalog examples range from the compact ETT-01D1A102-00 in Emhiser’s smallest 01 (1.3 cubic inch) package at 1 W output, up to 5-watt ETT-05D1A502-00 units in the 05 (5 cubic inch) package, with additional EB-band (2200-2400 MHz) variants such as ETT-01EBA151-00. All units run from AC-coupled power supplies and are designed for direct mounting in airborne telemetry instrumentation pods, missiles, munitions and aircraft test articles. As Emhiser’s longest-running transmitter family, the Telemetry Transmitter series has been supplied to U.S. military branches, DoD contractors and space agencies for range telemetry on both prime and sub-prime programs, and is documented in Emhiser’s dedicated Telemetry Transmitters catalog covering the full range of frequency, power and package combinations.
