Jammer Application

admin — Mon, 03 Oct 2011 23:34:44 +0000

Electronic Countermeasures (ECM) encompass several types of systems, one of which is a jammer. A jammer is a device that emits RF energy to disrupt sensor signals, such as RADAR, or communication signals used by an enemy. Jammer systems range from simple noise emitters, such as barrage jammers, to more sophisticated systems such as deception repeaters. A growing area of interest is the Counter-IED application that jams communication signals used to activate improvised explosive devices (IEDs).

This application note shows how a generic jammer system, a system that can be used to detect, lock onto and jam threat signals emitted by an enemy, can be implemented on its SDR-4902 system.

SDR-4902 Solution

The SDR-4902 is an integrated solution that provides the RF and digital processing chain in a two card solution. Configured in a compact desktop air-cooled chassis, the SDR-4902 operates in the 200 MHz to 2.7 GHz frequency range, enable one system to support multiple bands based on your application. The system supports fast frequency hopping waveforms (up to 3000 hops/sec with 10:1 dwell-to-tune time ratio).

Obsolescence Management Service

admin — Wed, 20 Jul 2011 19:47:42 +0000

Upon product end of life (EOL), we work with our customer to prepare a unique Obsolescence Management Plan that specifies the quantity of product required over a duration of time. Last time buy (LTB) quantities of the component(s) going obsolete is placed into bonded inventory. The components placed into bonded inventory is customer-owned material. Spectrum monitors the product bill-of-materials (BOM) for further component obsolescence. Upon such occurrence, Spectrum notifies the customer of the additional component(s) EOL and works with the customer to update the Obsolescence Management Plan.

Component Management System

Spectrum product BOMs are continuously monitored for component obsolescence and/or other component changes using a state-of-the-art component database monitoring facility. Upon receiving component change/obsolescence notification, we work with our customers to update their existing Obsolescence Management Plans to effectively reset the EOL clock. Proactive BOM monitoring provides Spectrum and our customers the ability to react quickly to critical information maximizing product
life cycle and associated revenue.

Bonded Inventory

Based on the needs of the customer specific Obsolescence Management Plan, a LTB for components going obsolete will be purchased as customer-owned inventory and bonded. Customers are given credit for the components used from the bonded inventory upon shipment of the product.
