MEGA-POLE® Series
MEGA-POLE™
-
The MEGA-POLE filter series covers the standard frequency bands within the 30 to 450 MHz range. This new filter series provides excellent selectivity while maintaining very low insertion loss. The product line also has exceptional RF power handling capability with a high third order intercept point. The MEGA-POLE filter series can be used for transmitter applications to reduce power amplifier noise, harmonics and intermodulation products, to provide bi-directional filtering directly at a transceiver’s antenna port, or other applications requiring extremely linear, high power RF bandpass filtering. It has been designed for rugged military environments per MIL-STD-810.

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.

Bench PIM Testing
iBA Series
-
Passive Intermodulation (PIM) occurs when multiple RF signals encounter defects in materials or workmanship in an RF path. These defects behave like a mixer causing noise to be generated at mathematical combinations of the original carrier frequencies. PIM interference that falls in the receive band of a wireless system elevates the noise floor resulting in high dropped call rates, call blocking, slow data transmission speeds and decreased system capacity. Kaelus is the industry leader in Passive Intermodulation test solutions. Since 1996 Kaelus has supplied RF equipment manufacturers around the world with precision IEC compliant test equipment to perform this critical test. From initial product design through high-volume manufacturing, Kaelus offers a wide range of PIM test solutions that enable equipment manufacturers to quickly and confidently verify the performance of their products.

Audio Generator
AG-51
-
The AG-51 Audio Generator contains a low distortion 20 Hz to 200 kHz sine wave generator, an SMPTE standard intermodulation signal generator and a fixed frequency sine wave generator at 3.15 kHz for wow and flutter tests. Signal outputs are simultaneously available at levels of up to +20 dBm (equivalent sine wave power for complex signals) at separate left (L OUT) and right (R OUT) output connectors. Outputs may be selected for left (L) only, right (R) only, left and right in phase (L+R), and left and right in phase opposition (L-R). Fully balanced or unbalanced outputs at impedance levels 150 ohms or 600 ohms are front panel selectable. Three precision attenuators (10, 1.0 and 0.1 dB) provide a dynamic range of 99.9 dB in 0.1 dB steps. Attenuator dials display the output level directly in dBm in the 150 ohm source impedance configuration. Automatic output leveling circuitry with a built-in self-test feature provides a constant output level thereby eliminating the need for output metering. In the TEST mode the generator output level is reduced to zero, a useful feature during noise measurements.

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.
