The SMJ1890 is a cellular jammer that can block cellular networks and standards worldwide. It uses DDS and PLL technology to jam up to 100W per band across 4 bands, jamming up to 60 channels within each band. It has an adjustable output power between 5W and 100W and can jam both downlink and uplink signals simultaneously. The jammer transmits noise to block cellular communication between phones and towers within its radius.

General Description
The SMJ1890 was designed for blocking GSM cellular network and
all kinds of cellular standards in the world.
The SMJ1890 is using state-of-the art technology for maximum
performance.
The unit is controlled by a Microprocessor for PLL & DDS
programming.
The unit was designed with the capabilities of jamming specific
channels inside the cellular networks bands only.
Jamming of downlink & uplink is possible at the same time.
The unit is based on a DDS that can be programmed to transmit up
to 36 channels per band, by fast sweeping between each other.
Channel bandwidth is 250 KHz.
The user can control output power of each band via a programmable
attenuator.
Output power can vary from 5W up to 100W within 1dB steps.
The SMJ1890 transmits noise signal which cuts-off all cellular
communication between mobile phones and cellular base stations.
The jamming radius depends on the signal strength in a given area.
All cellular mobiles in vicinity to the SMJ1890 will be totally
BLOCKED and will not be able to receive or dial outgoing calls.
