FrequencyDC-3GHz
Average Power2W
Range10dB

For perfect matching sometimes it is required that the microwave power in a waveguide be absorbed completely without any reflection and also insensitive to frequency. For this Waveguide Variable Attenuator is used. Attenuators are commonly used for measuring power gain or loss in dBs for providing isolation between instruments, for reducing the power input to a particular stage to prevent overloading. It provides continuous attenuation of power upto 20 dB.

Minimum Order Quantity: 1 Piece

Material UsedBrass
ShapeT-shape

A Tunable Probe helps in detecting the low-frequency square wave modulated microwave signal. It is made by the use of crystal diode mounted in the transmission line. The probe is connected to the crystal detector so that the output of the detector is proportional to the square of the input voltage at the position of the probe. As the position of the probe is moved along the waveguide slot, it gives an output proportional to the standing wave pattern inside the waveguide.

Slotted Section Waveguide consists of a transmission line (waveguide), a traveling probe carriage and facility for attaching/detecting instruments. The slot is made in the center of the broad face that does not radiate for any power of dominant mode. The slotted section is basically used to measure standing wave ratio (VSWR). The precision built probe carriage having centimeters scale with a vernier reading of 0.1 mm, least count is used to note the position of the probe. Additionally, the slotted section can be used to measure impedance, reflection coefficient, and the return loss.

Klystron Mount Waveguide Components are the waveguide of suitable length having an octal base on the broad wall of the waveguide for mounting the klystron tube. It consists of movable short at one end of the waveguide to direct the microwave energy generated by the klystron tube. A small hole located exactly at the center of the broad wall of the waveguide is used to put the coupling pin of the tube as the electric field vector of EM energy is maximum at the center only. The maximum power transfer can be achieved by tuning of the movable plunger.
