<strong>Mobile</strong> <strong>Jammer</strong> <strong>MJ</strong>-1<br />
Art.-No.: 250001<br />
DESCRIPTION<br />
Our mobile jammer <strong>MJ</strong>-1 is intended for protection against the activation of radio controlled<br />
improvised explosive devices (RC-IEDs).<br />
This system can prevent activation of RCIEDs and therefore signifi cantly reduce the distance<br />
for bomb activation.The <strong>MJ</strong>-1 can also be used to jam radio communication systems<br />
to support Special <strong>Force</strong>s operations.<br />
This jammer allows the usage of very effective band limited exciters and high gain multiband<br />
antennas in higher frequency bandwidths.The RF power management is optimized to<br />
offer a good effi ciency of the system.<br />
The jammer covers the most threatened frequency bands and is equipped with 10 wideband<br />
transmitting subsystems covering crucial frequencies which can be misused for triggering<br />
improvised explosive devices.<br />
It works in bandwidths from 20 MHz up to 2,5 GHz, fully covering 20 MHz to 500 MHz as<br />
well as GSM, DCS, UMTS, WiFi, Bluetooth, WiMax.<br />
All bands are equipped with an own exciter and power amplifi er.<br />
The frequency bands up to 500 MHz, GSM and DCS are completely digital with very short<br />
preset dwell times.<br />
Frequency steps can be preset with 1 Hz precision.<br />
Bands of UMTS and WiFi are equipped with the digital arbitrary waveform generators offering<br />
the possibility of changing the type of the jamming signal (e.g. white noise or sweep).<br />

<strong>Mobile</strong> <strong>Jammer</strong> <strong>MJ</strong>-1<br />
Art.-No.: 250001<br />
SPECIFICATIONS<br />
Further important features are the easy operation, advanced self diagnostics and built-in<br />
test equipment (BITE).<br />
The mobile jammer <strong>MJ</strong>-1 and its transmitting subsystems can be remotely monitored and<br />
operated using an optical cable connection.<br />
System is offered with omnidirectional wideband or multiband antennas with a gain of at<br />
least - 7 dBi.<br />
The jammer antennas are intended for installation on a vehicle roof and bumpers.<br />
Frequency bands down 500 MHz are equipped with low pass fi lters for improving the electromagnetic<br />
compatibility of the system.<br />
The jammers are embedded in two stand-alone independent racks with different height<br />
(HU). These racks should be installed in the rear compartment of a vehicle.<br />
The system can be controlled using the portable remote control unit (RCU) placed beside<br />
the driver, which allows switching ON/Off particular bands, indicates wrong VSWR, transmitter<br />
fault and excessive heat.<br />
The system produces heat loss during the operation, namely due to the power amplifi ers<br />
working in AB linear class, and is working air-cooled.<br />
The RCU can be customized according to customer requirements.<br />
The system fulfi lls the requirements of a customer within the following conditions:<br />
- Scenario1 – bands to 500 MHz<br />
The insurgent person with triggering radio equipment will be located 100 metres<br />
from the IED; the power of the radio equipment is 2 Watts. The effective protection<br />
rangeof the jammer is at least 40 m.<br />
- Scenario 2 – digital communication infrastructures<br />
Different situation for infrastructural communication systems (GSM, UMTS, DCS):<br />
There are defi ned levels from the closest BTS (for -70 dBm).<br />
The protection range is at least 70 m (according to the situation).<br />
