2 FLEXIBLE WAVEGUIDE 170FT SERIES 170S SERIES R170FT SERIES R170S SERIES No. T21E 1 OF 4 Because of its many unique characteristics, Flexible Wavguide has found wide use as a component in microwave equipment. System and laboratory problems associated with shock, vibration, tolerance take-up due to misalign-ment or temperature variations, ease of assembly and disassembly, etc., are ideally solved by inclusion of this versatile transmission medium. SEAMLESS & SIDESEAM CORRUGATED FLEXIBLE WAVEGUIDE MEC s Rectangular and Double-Ridge Seamless Corrugated Flexible Waveguide are made by convoluting seamless tubing. Rectangular waveguide sizes larger than WR-137 are made Sideseam. All units are inherently pressure-tight, highly stable, rugged, and have no R-F leakage. They will bend more than the flexible-twistable types but cannot withstand any twisting. Bends are semipermanent and small bends radii should be factory formed. Unless requested, units are supplied without jacket or silver plating. 170S SERIES R170S SERIES FLEXIBLE-TWISTABLE WAVEGUIDE (FOR SPECIAL APPLICATIONS) Microwave Engineering Corporation s Rectangular and Double- Ridge Flexible-Twistable Waveguide are of the convoluted type of construction. They are precision-wound in accordance with strict design standards, which assure long life and excellent electrical performance. Adjacent turns are securely crimp-locked together forming a continuous joint. All units are supplied with a molded jacket of neoprene and are available with MEC s Flangelok Molding Process, which eliminates flange separation problems under conditions of extreme tension. 170FT SERIES Besides the standard units described on the following pages, Microwave Engineering Corporation produces many special assemblies such as twists and pre-formed bends to much smaller radii to satisfy unique requirements. Additionally, combinations of rigid and flexible waveguide, jacketed or unjacketed, with built-in pressure/relief valves, quick-disconnect flanges, etc., are readily available. All units are manufactured in accordance with strict design standards, which assure long life under adverse field conditions. R170FT SERIES 4-1 Data subject to change without notice

10 RECTANGULAR & DOUBLE-RIDGE WAVEGUIDE ASSEMBLY MANUFACTURING No. B20E 5 of 7 MEC-Built Automatic End Sizing Machine Specialized machining processes are used on long production runs to assure high quality rapid machining of assemblies. Stringent requirements of flange parallelism and perpendicularity necessary for proper system installation and performance are easily met. The flanging process employed by these machines assures true-position tolerancing of all necessary dimensions from the centerpoint of the waveguide opening, not from nominal outside dimensions. Specially Designed Miller Automatically Machines Flange In Place On Waveguide Close-up Of Flange Cutting Facilities for interior and exterior finishing of completed assemblies are maintained in-house at MEC. Chemical cleaning, chromate conversion, painting and plating facilities adhering to strict military standards enable us to maintain tight controls of production schedules. Careful final mechanical inspection, plus 100% R-F testing of all components is the rule at MEC. Inspection procedures in accordance with MIL-I-45208a are maintained. Complete R-F test labs with 1 90 GHz frequency capability, as well as high power and environmental test facilities to simulate actual system situations allow complete confidence in system performance.

13 WAVEGUIDE QUICKCLAMPS TQ SERIES No. T301 Construction: The clamp assembly of our quickclamps is a single body construction. The only separate items are the flange locating pins and the mounting hardware. Operation: Opening and closing requires only one hand. Clamping action is a toggle which is self holding once the handle is closed. Safety Latch: Safety latches which prevent accidental opening are available for the waveguide sizes listed in the table. These latches are not part of the positive holding assembly, but are separate devices. They operate automatically when the quickclamp is closed, but must be tripped manually to open. Size: Quickclamps for the waveguide sizes listed in the table are readily available. Other sizes can be supplied upon request.
