Waveguide Phase Shifter

• Model 3045 E-H Tee consists of a section of waveguide with both cseries and shunt waveguide arms, mounted at the exact mid point of main arm, Both ends of the section of waveguide and both arms are flanged on their ends.
• These Tees are employed in balanced mixers, automatic frequency control circuits and impedance measurement circuit etc. This becomes a four terminal device where one terminal is Isolated from the input terminal.

• Model 2051 klystron mounts for mounting corresponding Klystrons such as 2K22, 2K25, 723A/B, 726A or RK-5976 etc
• These consists of a section of waveguide flanged on one end and terminated with a movable short on the other end . An octal base with cable is provided for connecting these mounts to klystron power supply(Model KP-151).

• Model 3145 Matched Magic (E-H) Tee is similar to model 3045 E - H Tee except thatits all the four ports are matched to a max. VSWR of 1.40 over the ±15% frequency range. This is achieved by inserting a matching piece in the waveguide with a stub. Whenever a matched Tee is needed, please mention the center frequency needed.
• These are available in all the frequency- bands e.g. L, S, C, J, X, Ku & R-bands etc.

• Model 6055 Tunable-Probes are designed for use with Model 6051 Slotted Sections. These are meant for exploring the energy of the electric field in a suitably fabricated section of waveguide
• The depth of penetration into a waveguide-section is adjustable by the bottom knurled knob of the probe. The tip (central wire projection of the probe) pickup the RF power from the line and this power is rectified by crystal detector, which is then fed to the VSWR Meter or indicating instrument. The Knurled top knob is used to maximize the power bymoving it up and down.
• This is compulsorily required with each slotted section model:6051

• Model 4051 Tunable Detector Mounts are simple and easy to use instruments for detecting microwave power through a suitable detector
• These consist of a detector crystal mounted in a section of waveguide flanged on one end and a shorting plunger for matching purpose on the other end. The output available at BNC (F) connector from the crystal may be fed to an indicating instrument
• In K and R bands detector mounts the plunger is driven by a micrometer.

• Model 4155 waveguide Matched Detector Mounts (fixed type) operate over full waveguide frequency bands and these are useful for those applications, where sensitivity is less important.
• These consists of a section of waveguide with short on one end and flanged on the other end. In these detector mount a more sensitive detector with a resistive disc for matching purpose is used. Output connector is BNC(F).

Model 9180 Waveguide Phase Shifter( Micrometer Type) consists of a section of waveguide flanged on both ends with a dielectric vane, which is movable by means of a micrometer inside the waveguide. These Phase Shifters provides a phase-shift of around 180°. A calibration - chart giving micrometer reading vs Phase Shift at particular frequency is provided with each unit.

Note: Precision Waveguide Phase-Shifters using Rotary-Vane principle for 0-360° shift are also available.

• Model 5035 waveguide stands are meant to accept the components of respective bands for setting up a waveguide test bench and system.
• The height of stand is adjustable with a locking screw.These consists of a C.I. base with supports of different frequency bands.
• Frequency-band designations L, S, C, J, X & Ku suffices may be added to the 5035 model, when ordering (e.g. X-5035 for X-Band).
• Clamps for K, R, V & W-bands have adjustable width to hold cor responding waveguides of Millimeterwave Components.

• Model 7051 Waveguide Twist is used, whenever a 90 Degree change in the plane of polarization in awaveguide system is required.
• These consists of a section of waveguide which is0 0 mechanically twisted through adject 90 (±1 ) andthe waveguide cross-section is maintained uniform through out its length.
• Waveguide twists with other than 90 orientationare also available.
• Waveguide Twist in 1.0 to 4.0 GHz range are available in 3 or 5 waveguide sections joined together to give the desired orientation

• Model 6155 Broad Band Tunes Probes are fixed and matched probes for use with model 6051slotted sections. These probes are simpler in use as no tuning is needed, and may be used for broad frequency ranges.

• Model 602I Isolator consist of Three port Circulator with one port terminated by Matched Load (Termination), thus making it a two port device.
• These are well matched devices offering low forward insertion loss & high reverse isolation.

• Model 602T and 602Y are T and Y types of three port circulators respectively . These are precisely machined and assembled to get the desired specifications.
• Circulators are matched three-port devices and these are meant for allowing microwave energy to flow in clockwise direction with negligible loss but almost no transmission in the anticlockwise direction.

• Model 3045 E-H Tee consists of a section of waveguide with both cseries and shunt waveguide arms, mounted at the exact mid point of main arm, Both ends of the section of waveguide and both arms are flanged on their ends.
• These Tees are employed in balanced mixers, automatic frequency control circuits and impedance measurement circuit etc. This becomes a four terminal device where one terminal is Isolated from the input terminal.
