Waveguide Filters

Model 9051 transitions are meant for connecting the circular waveguide to the corresponding rectangular waveguide or vice versa. These are so designed to give lowest VSWR through out the frequency band

These  are  fabricated  by  precise  and  well-controlled electroforming process

Please mention the size & drawing of the flanges particularly on the round waveguide side.

These filters can be fabricated as per customer's requirements. The following specifications should be mentioned for fabrication:-

Low-Pass, Band-Pass or High-Pass

• Band-width (frequency)
• No. of n-section & size
• Max. Insertion loss & min. Isolation etc.

• Mode 8051 Waveguide Switches are 3 Port mechanical devices. They transfer power form port-1 to either Port-2 or Port-3, These are manually operated by a knob.
• These have rugged construction, with H-Plane bend made to rotate in the stationary outer portion of these switches.

Model 5041 Pyramidal Waveguide Horn consists of a Section of waveguide joined to a pyramidal section fabricated from brass sheet. This pyramidal section shapes the energy to concentrate in a specified beam.

Waveguide Horns are used as feed horns or as radiator for reflector and lenses and also as a Pickup antenna for receiving microwave power.

Waveguide Horns can also be fabricated in Aluminium material.

Waveguide Horns with lower or higher gains e.g. 10, 20 db are also available 

• Model 5101 is a Conical Antenna with approx. gain of 15 db. It has round wave guide on one end and conical body with round aperture on the other end.
• A Circular to Rectangular Wave guide Transition (Model 9051) is required to connect this antenna with rectangular wave guide test-systems.

• Model : 5161 and 5163 are the slotted waveguides with slots in broad wall and narrow wall of the waveguides respectively. These slotted waveguides are flanged on both ends.
• Dielectric Antenna or any other antennae can be fabricated.

• Model 4151A, B & C Coaxial Detector Mounts are coaxial untunable type fixed Detector Mounts for use with coaxial outputs. These are low SWR devices having 
• flat frequency response and high sensitivity.
• These consists of N (M) connector on input side and BNC (F) connector on Output side and a crystal diode with matching disc is mounted inside.

• Model AT-211B is an automatic self balancing Power Meter. It measures RF Power with the help of temperature compensated Thermistor Mount from 10µW to 10mW fullscale with 1% accuracy from 10 Mhz to 40 Ghz (depend upon type of Thermister Mount)
• With calibration factor control switch, AT-211B normilises the Power Meter reading to compensate the efficiency of used Thermistor Mount.
• AT-211B has provision for substitution measurements and Power Meter calibration. Output is provided for recorder or Digital Voltmeter readout.

• Model 5145 Tripod Stands are made toV hold the antenna. 
• This is useful for plotting the polar pattern of antenna.
• It consists of a triangular steel base with leveling screws, on which three legs are 0 connected to a block. A 0-360 round scale is provided to read the rotation of antenna. The height of antenna is adjustable from 110 to 150 cms.
• These are available for S, C, J, X, Ku, K and R-bands.

• Model 5043 and 5045 are E-Plane and H-Plane Sectoral Horns to provide the gain (15db) in E-Plane and H-Plane directions respectively. 

• Model 5061 Pick-up Horn is similar to Pyramidal Horn except that it has square aperture. These are use as feed for Dishes etc.
