* Power Passing or No Power Passing
(alternative)
* F type Male or Female connectors
can be selected at one or both sides
* Suitable for CATV, satellite and
other communication systems
Most satellite receivers are designed to operate with input signal levels between -60dBm and -30dBm per channel, TVs for input signal levels between -48dBm and -23dBm.
If feed signal levels to satellite receivers or TVs are too high, picture distortions will occur.
It is recommended that by inserting an attenuator into the distribution system, the signal is reduced to less than -30dBm or -23dBm at the customer outlet.
The AT1-7 series is able to meet the needs of general-purpose attenuation applications in the LF/VHF/UHF and Satellite-IF frequency range.
The specification, from 15MHz to 2300MHz at 100mW average, 250mW peak, low VSWR(<1.30 at 1000MHz) and good accuracy (1dB at 2GHz). (see the figure)
