◆TC-5060 TEM Cell Product Description
TC-5060B TEM Cell, is an economical UHF TEM Cell which generates a consistent Electromagnetic field for testing small RF devices such as Pagers, GPS Receivers, Mobile Phones, etc. An external test signal applied through the input port of the TEM Cell, TC-5060B TEM Cell 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 measurements beyond the the standard TEM Cell frequency range.
◆TC-5060 TEM Cell Theory of Operation

The TESCOM TC-5060B UHF 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 GTEM Cell. The size of the GTEM design is too large for typical small device applications due to the type of absorber used. TESCOM borrowed the concept of GTEM, 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-5060B TEM Cell 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.
