The TC5062 TEM Cell is your ideal test Cell to compliment your test equipment in a small package but offering the ability to simulate a far field in a near field environment. TEM Cell, is an economic UHF TEM Cell which generates a consistent Electro-magnetic field for testing small RF devices such as RFID, GPS Receivers, cell phones, and other wireless devices. An external test signal can be applied through the available RF side port of the TC5062 TEM Cell which generates a consistent and predictable TEM test field inside the cell.
If you need to incorporate the benefits of a TEM cell into manufacturing or high volume testing, the TC5063C is your best bet as it offers all the benefits for consistent repeatability in testing but with the added feature of remote pneumatic control.
TC-5062 TEM Cell Description
TC-5062C, 6 GHz TEM Cell generates the Electro-Magnetic field for testing small RF devices such as wireless communication receiver, Mobile phone, etc. An external test signal applied through the input port of the TC-5062C generates a consistent and predictable TEM test field inside the cell. The radiation field from a device transmitting in the Cell can also be detected through the port using a test receiver.
The unique compact and economical design is optimized for medium accuracy measurements beyond the standard TEM Cell frequency range.
Theory of Operation
TC-5062C 6 GHz TEM cell is made to work beyond the typical TEM Cell operating frequency range limited by cell resonance. A typical TEM Cell is a 2-port symmetrical device; RF voltage is applied to one port while the other port is terminated in 50 ohm while maintaining 50 ohm characteristic impedance along the cell. Due to expansion and contraction parts of the cell, the wave propagation beyond certain frequency is no more propagated by TEM mode alone and creates resonance. To eliminate the resonance problem, the half of the cell is replaced by the wave absorbing material. One commercial implementation is G-TEM cell. The size of the GTEM design is too large for typical small device applications due to the type of absorber used. We borrowed the concept of G -TEM, but changed the termination implementation scheme, and designed a very compact broad band TEM Cell that can be used on a desktop.
The operation principle of TC-5062C is essentially the same as TEM Cell. The E-H field inside the test volume is proportional to the input voltage and inversely proportional to the cell height. If a radiating object is inserted inside the cell, the radiated wave toward input port is guided by the transmission line and picked up at the input with a receiver such as a spectrum analyzer. With this method, the RFI from a radiating Device can be measured quantitatively. Since this apparatus is very broadband, it has many applications in the area of EMI, EMS, receiver sensitivity test, etc.
