AbstractHerley Industries has applied state of the art design for production techniques to develop of a line of dual use spectrally efficient digital data transmitters. Herley has been a global leader in the design and production of high tech RF and microwave products for more than 30 years. The resulting transmitters support variable data rates up to 20 Mbps and output power levels to 10 Watts in both the L and S frequency bands. The transmitter product line implements Feher’s-patented Quadrature Phase Shift Keying (FQPSK) modulation technique, effectively doubling the spectral efficiency of conventional PCM-FM techniques. While the development of this transmitter product line represents the initial offering of Herley in the blossoming FQPSK industry, the design team has relied upon its extensive experience in producing RF and microwave products that represent the state of the art in design and manufacturing techniques. The end result has been the production of cost effective transmitters that meet the vibration, shock, EMI, altitude, and temperature requirements of missile and aircraft environments.
