Product Description

Well suited for "Over-the-Air" testing of RF devices, the TC-5060A/B, RF TEM Cell generates a uniform Electro-Magnetic field for testing small RF devices such as pagers, GPS Receivers, Portable phones, PDAs, etc.  Through its input port mounted on the top of the Tem Cell, an external test signal may be applied to generate a predictable TEM test field within the cell.  The radiation field can also be picked up through the input port using a test receiver. Our TEM Cell also provides a high degree of RF Isolation from the outside environment which is mandatory for accurate and consistent test data,  Its also incorporates both RF and data feed throughs. 

  Theory of Operation

TC-5060A/B UHF TEM Cell 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 of 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 a G-TEM cell. The size of a G-TEM design is too large for typical small device applications due to the type of absorber used.  We borrowed the concept of the 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 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.
