| Authors:
James L. Alford; Donald G. Jackson; ALEPH INC GARLAND TX
|
| Hybrid thick film technology from its inception provided a capability that cannot currently be duplicated by any other solid-state active device process. This program explored the utilization of this technology by breadboarding various versions of low-power communications devices. It was established that the technology is capable of producing high yield, reasonable cost equipment of extremely miniature size, high efficiency and low power consumption. The potential applications explored were not all ... |

|
| An Arctic Service test was conducted on Low Capacity Army Area Communications (AACOMS) Assemblages AN/TCC-65, AN/TRC-145, AN/TRC-113 and AN/MRC-127, by the U. S. Army Arctic Test Center at Fort Greely, Alaska, from 1 September 1969 to 30 January 1970. The test was conducted to determine to what degree each of the subject assemblages and their associated tools and test equipment perform their mission and to determine the operational capability of ... |

| (1) Z14-M4 Broadband Solid-State Sweep Generator - With this new all-solid-state sweep generator one can dial F1 and F2 from 1.0 to 12.4 GHz or anywhere in between, then depress F1 and F2 buttons, and sweep the frequency with no interruption for changing plug-ins, cranking, or dial resetting. In effect, when using this modern, advanced concept instrument, the usual 'octave' limitation does not obtain. One can select any combination of ... |

|
| Extends the usual Bayes analysis for optimum detection systems to include the costs of equipment, location, maintenance, and operation. Also included are the customary preassigned costs for correct and incorrect decisions when passive sensors at multiple receiving sites are used to acquire and process data as to the presence or absence of a signal source. A risk formalism is constructed that indicates how the expected overall costs of both decision ... |

| The Pilot Injector Group is inserted between the channel multiplexer output and the group multiplexer input to inject the 104-080 kHz pilot frequency and amplify the signal to insure the output impedance is 135 ohms. It also contains a 104.080 kHz band elimination filter to block stray signals before the pilot frequency is injected. The group is variable and can be equipped with up to five groups by selecting the ... |

|
| A number representation scheme is described which can be applied to frequency synthesizers such as are used in communication transmitters and receivers. The scheme permits a very large number of frequencies to be constructed from a much smaller set of fundamental (basis) frequencies. This approach may be applied to a variety of different communication requirements, such as airborne or portable equipment where weight or volume limitations are important, and wideband ... |
