PolyPhaser Combiner Products

CS & PS SERIES
Sampler Port Cellular/Paging Combiner Coaxial Protector

PolyPhaser developed the Combiner Series to eliminate the sharing of center pin surge current common to 1/4 wave stubs and other dc continuity protectors. The patented PolyPhaser protectors have center pin dc blocking and have as much as 60dB more attenuation of lightning frequencies than 1/4 wave devices.

UNDERSTANDING THE SAMPLER PORT

A number of protectors are sold on the premise that they will reduce the number of connectors needed Ľn the cable system. At some time it will become necessary to sweep or TDP test your cable or antenna. Ths cannot be accomplished with a 1/4 wave filter in line. An RF sweep will be colored by the 1/4 wave and will not show the true frequency versus return loss or (VSWR). A TDR pulse will not pass through the 1/4 wave.

With PolyPhaser's Sampler Port Series, preventive maintenance and troubleshooting can be accomplished without removing the protectors. The Sampler Port with its BNC connector coupled to tne antenna line permitting the port to be used for "on-air" relative spectrum analysis (signal strength at discrete frequencies can be noted for future comparisons), TDR testing, power monitoring, RF sweeps, and protector testing.

The port is buffered by a parallel tuned circuit which provides a minimum of 20dB (typically 30dB) attenuation of the transmit signals. The inductance will show on a by resolution TDR response as a small discontinuity but the location will be obvious. For a 2ns TDR pulse, the total pulse loss is -3dB, round trip.

 



 

APPLICATION:

Designed for 800 to 980MHz bands with multi-channel or combined transmitters. Sampler Port provides access for on-air spectrum analysis without removing the protector.
