Antenna, Wideband Discone
EM-6115 | 10 KHz – 2 GHz
The EM-6115 is a broad band collinear array allowing very wide Omni-Directional frequency coverage in a single package. Below approximately 100 MHz, the EM-6115 acts as an active vertical rod which offers 10 to 12 dB Greater unsaturated instantaneous dynamic range than competitive antennas (overload field strength: 2 V/meter) which greatly reduces intermodulation generated signals in a typical read world RF environment. In the congested spectrum above 100 MHz the antenna is passive and contributes no intermodulation products so the overload point is determined solely by the receiving instrument. This immunity to overload can often make the difference between useful signal output and an indecipherable jumble of spurious products and is accomplished without compromising sensitivity. The antenna collapses for convenient storage and transport.

Coaxial Switches
An electromechanical switch made primarily for routing microwave signals/RF energy from one point to another within a transmission line. Coaxial switches can be used in either an industrial environment or in the lab. These electromechanical devices are also used for RF testing equipment and in large RF communication systems and networks. Coaxial switches vary by port configuration, switch type, maximum frequency, isolation, insertion loss, voltage standing wave ratio (VSWR) and package type. Coaxial switches are able to route RF signals over a broad bandwidth from DC to 40 GHz, and are now offered with the Low PIM option which will improve Passive Intermodulation levels from -110dBc (standard switch) to -160dBc.

PIM Testing
Rosenberger Hochfrequenztechnik GmbH & Co. KG
Passive Intermodulation (PIM) is a non-linear response of two or more signals of different frequencies mixing together in a passive device, e.g., antenna, cable, con- nector or splitter. Today, PIM has become a very serious, and challenging issue for mobile operators, equipment vendors, and component manufacturers due to frequency planning in modern communication networks, the usage of high-power transmitters and the usage of more sensitive receivers in base stations. If a PIM with sufficient magnitude generated from a transmitter falls within an adjacent receiver channel, it causes serious interfe- rences to the base station receiver and will significantly degrade the network quality of service.
