◆ productiondesc-ription

tc-5062a, economy uhf tem cell generates a consistentelectromagnetic field for testing small rf devices such as pagers,gps receivers, mobile phones, etc. an external test signal appliedthrough the input port of the tc-5062a generates a consistent andpredictable tem test field inside the cell. the radiation fieldfrom a device transmitting in the cell can also be detected throughthe port using a test receiver. the unique compact and economicaldesign is optimized for medium accuracy measurements beyond thestandard tem cell frequency range.

◆ theory ofoperation

tc-5062a uhf tem cell cell is made to work beyond the typicaltem cell operating frequency range limited by cel resonance. atypical tem cell is a 2-port symmetrical device; rf voltage isapplied to one port while the other port is terminated in 50 ohmwhile maintaining 50 ohm characteristic impedance along the cell.due to expansion and contraction parts of the cell, the wavepropagation beyond certain frequency is no more propagated by temmode alone and cr-eates resonance. to eliminate the resonanceproblem, the half of the cell is replaced by the wave absorbingmaterial. one commercial implementation is g-tem cell. the size ofthe g-tem design is too large for typical small device applicationsdue to the type of absorber used. tescom borrowed the concept ofg-tem, but changed the termination implementation scheme, anddesigned a very compact broad band tem cell that can be used on adesktop.

the operation principle of tc-5062a is essentially the same astem cell. the e-h field inside the test volume is proportional tothe input voltage and inversely proportional to the cell height. ifa radiating ob-ject is in-serted inside the cell, the radiated wavetoward input port is guided by the transmission line and picked upat the input with a receiver such as a spectrum analyzer. with thismethod, the rfi from a radiating device can be measuredquantitatively. since this apparatus is very broadband, it has manyapplications in the area of emi, ems, receiver sensitivity test,etc.
