TC-5062C 6 GHz TEM Cell
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 .联华行 The unique compact and economical
design is optimized
for medium accuracy
measurements
beyond the standard TEM Cell frequency range.
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 G-TEM design is too large for
typical small device applications due to the type of absorber used . TESCOM 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
