In wireless communications, linearization of the PA is sometimes required to ensure high quality of the modulated signal and maintain good PAE. PA linearization using a feed-forward technique 1–4 can be very tedious and time consuming. Without PA linearization, an approach to achieve high power and good PAE is...

Rapid progress in telecommunication and radar technology is placing increasing demands on wireless system performance. Such demands include high information capacity and the ability to track multiple mobile targets or users. 1–3 Military research programs in particular are placing heavy emphasis on Network Centric Warfare, a wireless network concept...

RF power amplifiers (PA) are the last active blocks in any wireless transmitter system, handling the highest levels of RF signal and supply power. Linearization enforcing techniques relying on either adding external circuitry to the PA, or simply improving its design, 1 are thus necessary. However, since the first...

Northrop Grumman Corp. recently performed successful high speed captive flight tests of its multi-mode, air-to-ground terminal guidance seeker during moving-target engagement exercises at Eglin Air Force Base. The exercises, conducted by the US Air Force Research Laboratory, in cooperation with Northrop Grumman, the Boeing Co. and Rockwell Collins, successfully...

Raytheon Co. has been awarded a $151.3 M contract from the US Army Aviation and Missile Command to provide engineering services support to the Patriot air and missile defense program. The award to Raytheon’s Integrated Defense Systems (IDS) provides funding for the first of four, one-year options, to last...

Lockheed Martin announced that it has delivered the first modernized Global Positioning System (GPS) satellite to Cape Canaveral Air Force Station, FL, where it will be readied for a May launch. The satellite, designated GPS IIR-M1, is the most technically advanced GPS satellite ever developed and will provide significantly...

The Air Force’s fleet of E-8C aircraft will receive updated air-traffic management systems under a $103 M, three-year system design and development contract recently awarded by the Electronic Systems Center at Hanscom Air Force Base, MA, to Northrop Grumman Corp. The avionics of the E-8C Joint Surveillance Target Attack...

QinetiQ and its partners AMS and Roke Manor Research have begun work on the Advanced Radar Technology Integrated System Test-bed (ARTIST). This £8.1 M UK contract is to build a research demonstrator system and assess techniques to support the next generation of maritime multifunction radar (MFR). The 44-month programme...

Smiths Group plc is expanding the range of technologies offered by its Detection division, with the acquisition of Farran Technology Ltd. The company, which is based in Cork, Republic of Ireland, is owned by its local founders, its management and two Irish venture capital funds. Smiths is acquiring the...

Alcatel and Intel Corp. have announced that both companies have expanded their strategic alliance on WiMAX, entering into a new joint development agreement. Both companies have committed to work closely together to expedite the delivery of end-to-end residential, nomadic and ultimately mobile WiMAX solutions based on the IEEE 802.16e...
