Parisier, Co. 1860 Broadway New York 23, New York Circle 5 -5700 TR A type for every known application - all bands ixed -tuned or tunable - cial types: shorted, dual d triple. ATR All standard types and many more developed in our labcratories nearly all fixed -tuned - highly specialized as required: low or high Q, miniaturized, eclat shapes and mounts. PRE -TR Several L -band and X -hand types, fixed -tuned - for operation at power levels of 550 and 3000 KW peak. SHUTTERS Bomac was the first to develop shutter tubes and integral TR combinations for continuous crystal protection. Today, the line includes a wide variety of tubes for the C, Ku, K, S and X bands. REFERENCE CAVITIES High precision, fixed -frequency, vacuum -sealed, transmission type for use in pressurized waveguide systems. Temperature compensatedt o ± 0.3 MC from 0' C to 100 C. HYDROGEN THYRATRONS Bomac thyratrons provide the following advantages: - precise triggering high repetition rates - high power levels - zero bias operation - electrieal stability. SILICON DIODES The most sensitive, uniform and stable diodes available (1N230). Also available In matched pairs for X -band and S -band. Can also be supplied as mixer diodes with either normal or reverse polarity. MAGNETRONS High frequency, tunable and fixed -tuned magnetrons are a Bomac speciality. Frequencies range from Ku to millimeter bands that are classified. Special types designed to meet your particular requirements. KLYSTRONS Bomac klystrons offer maximum performance at high altitudes without pressurization, and can be installed in existing systems without disrupting the associated equipment. DUPLEXERS Bomac will design, develop, and produce complete duplexers to customer specifications. PRESSURIZING WINDOWS Bomac has windows available for all wave guide sizes, broad band characteristics with low insertion loss, temperature range - 55° C to 100° C and 30 lb. sq. in. gage pressure in either direction. TRAVELING WAVE AMPLIFIER TUBES These Bomac tubes are designed to meet conditions where wide band high gain operations are required. Two types are available now - others will be available shortly. SYSTEMS Bomac engineers design, manufacture and assemble complete systems for any microwave band to meet your specific requirements. SURGE PROTECTORS Bomac surge protectors are hold -off diode tubes. A wide range of breakdown voltages is available: from 100 to 33000. Consult our engineering department for your particular applications. 01.-flac LABORATORIES, INC. Beverly, Massachusetts
