Klystron Based Advanced Microstrip Antenna Trainer TCM 022
The Microwave is a term used to identify electromagnetic waves in frequency spectrum ranging from 1Ghz to infrared region. The word microwave defines itself very short waves. The shortest wave length or the highest frequencies of radio spectrum are microwave. But these boundaries are not well defined.
Sci-tech Klystron based Advanced Micro-strip Antenna Trainer Model TCM 022, with Microwave Integrated Circuits (MIC) includes instruments and accessories for studying the characteristics of any MIC component over the frequency range 4 to 6 GHz.

TEST SET UP
Universal Test Jig
This jig has a spring mechanism, which is used to hold the microstrip components to be tested. It contains 6 SMA connectors to connect the various ports of DUT according to the components.
Microstrip Components:
- Low Pass Filter: It passes all the signals between zero freq. to some limit called the cut off frequency and attenuates other higher frequencies.
Specifications
The cut off freq. : 5±0.2 GHz
Insertion Loss : 3±0.2 dB
Return Loss : 15±0.5 dB
- Band Pass Filter : It passes all the frequencies in the frequency band between the lower cut off frequency to the upper cut off frequency and rejects the signals of other frequencies outside this band.
Specifications
The center freq. : 50-1.2 GHz
Insertion Loss : 1+0.2 dB
Return Loss : 20±1.0 dB
Bandwidth : 0.5 GHz
- Band Stop Filter: It passes all the frequencies outside the frequency band between the lower cut off frequency to the upper cut off frequency and rejects the signals of other frequencies inside this band.
Specifications
The center freq. : 5±0.2 GHz
Insertion Loss : 45±2 dB
Return Loss : 0.5+0.2 dB
Bandwidth : 1.0+10.2 GHz
- Ring Resonator: It transmits the signal at the resonance (design) frequency only and stops the signals of other frequencies.
Specifications
The resonance freq. : 5+0.2 GHz
Insertion Loss : 4+0.5 dB
Return Loss : 15±0.2 Db
- Branch Line Coupler: It is a four-port and 3-dB directional coupler with a 90 phase difference in the through and coupled outputs whereas the fourth port remains isolated.
Specification

Directivity : 18±2dB
Return Loss (Through) : 25±2dB
- Hybrid Ring (Rat Race) Coupler: It is a four-port coupler with a 180 phase shift and equal power division in the through and coupled outputs whereas the fourth port remains isolated.
Specifications:
Operating frequency : 5±0.2 GHz
Insertion Loss (At Through port) : 3±0.5 dB
Coupling : 3±0.5 dB
Isolation : 30dB(min.)(at design frequency)
Directivity : 25±2dB
Return Loss (Through) : 25±2dB
- Parallel Coupled Line Coupler: It consists of two close and parallel transmission lines and the coupled power depends on the separation between two lines.
Specifications
Operating frequency : 5±0.2 GHz
Insertion Loss (At Through port) : 1±0.5 dB
Coupling : 15±1.0 dB
Isolation : 23+2 dB
Directivity : 12+2dB
Return Loss (Through) : 20±2dB
- Power Divider (2): It is a three-port network, which divides the input signal into two equal output signals. Here two types of power divider are available: one is with chip resistor and another without it. The isolation between output ports increases due to chip resistor.
Specifications without resistor with resistor
Operating frequency 5+0.2 GHz 5+0.2 GHz
At O/P 1 I.L. 3±0.5 dB 3+0.5 dB
At O/P 2 I.L. 3±0.5 dB 3+0.5 dB
Isolation 8+2 dB 30±2 dB
Return Loss 25±2dB 35±2dB
- Patch Antenna (2): It radiates the microwave signal in the space or receives the microwave signal from the space. Two types of patch antennas are available: one is quarter wave transformer fed and another one is the inset fed.
Specifications Transformer fed Inset fed
Operating frequency 5+0.2 GHz 5+0.2 GHz
Return Loss 13±1.0 dB 8±1.0 dB
- Amplifier: It Increases the level of the microwave input signal with or without any phase change at the output.
