Low PIM frequency band loads suitable for DAS applications

A new series of telecommunications frequency band loads has been introduced by Link Microtek whose low PIM (passive intermodulation) characteristics make them particularly suitable for DAS (distributed antenna system) applications. They can also be used in other types of communications system where low PIM is required.

Utilising an internal coaxial cable to absorb microwave power, the LYNX series of loads feature a passive intermodulation distortion of less than -160dBc over their entire operating frequency range of 698-3,500MHz, together with a low VSWR of 1.25:1 and a return loss of 19dB. Nominal impedance is specified as 50Ω.

The loads can be supplied with either 4.3-10 or 7/16 DIN connectors and come in a choice of two models with average input powers of 200 and 100W, measuring 221x221x80mm and 221x100x60mm respectively.

Available from stock for quick delivery, these competitively priced loads have an operating temperature range of -20 to 65°C and offer a protection rating of IP67 to prevent the ingress of moisture and dust.
