FSK Transmitters (EFT Series)

The EFT FSK Transmitter series provides frequency-shift-keying (FSK) modulated RF transmitters used for digital data and command-link applications where FSK’s robustness to noise is preferred over wideband FM telemetry links. Catalog examples include the EFT-09D1D103 family (suffixes -00, -01, -02 for differing digital interface/coding options) in Emhiser’s 09 (9 cubic inch) package, operating in the 1435-1540 MHz D1 band at 10 W output with DC-coupled power, and related EFT-09D1D203 and EFT-09D1D502 variants covering different data-rate/power combinations, plus a D2-band (1710-1850 MHz) equivalent line such as EFT-09D2D103. These units are intended for airborne platforms needing a reliable digital FSK uplink or command transmitter counterpart to Emhiser’s analog telemetry transmitter lines, and are documented in Emhiser’s dedicated FSK Transmitters catalog (900 KB PDF).
