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.
