Ka-band SATCOM LNA The model APTW4-18002650-2510-42 is a waveguide (WR-42) amplifier that operates in a frequency range from 18 to 26.5 GHz. This model offers an ultra low noise figure of 2.2 dB (191.3 K) maximum and a minimum output power of +10 dBm (+20 dBm IP3). Optimized bandwidth...

Ultra Wideband Signals and Systems in Communication Engineering M. Ghavami, L.B. Michael and R. Kohno John Wiley & Sons Ltd. • 275 pages; $90 This book focuses on the basic signal processing that underlies current and future ultra wideband (UWB) systems. The introduction offers a brief look at why...

Microstrip antennas have recently gained wide popularity, because they exhibit a low profile, small size, lightweight, low manufacturing cost, high efficiency, and an easy method of fabrication and installation. Furthermore, they are generally economical to produce since they are readily adaptable to hybrid and monolithic integrated circuit fabrication techniques...

Frequency converters are rapidly becoming the only analog building block in a variety of RF and microwave systems. This trend is obvious in wireless consumer products, instrumentation, radar and radar-warning systems, telemetry and secure communications. The advent of synthetic instruments puts frequency converters at center stage within the RF...

Frequency synthesizers have been well studied, but difficult problems sometimes arise in their practical implementations. The major concern of synthesizer designers is the phase noise. It is critically important in Doppler radar, frequency-agile radar and various communications systems. In such applications, a synthesizer’s phase noise may set the system’s...

Harris Corp. announced that it has completed the installation and check out of all the equipment and services required for the transition of 24 major hubs to the new FAA Telecommunications Infrastructure (FTI) network. The transition moves an important portion of voice communication, flight data and weather information to...

The downlink phased-array antenna developed by Northrop Grumman for the Advanced Extremely High Frequency (EHF) military satellite communications payload has completed range tests that confirmed performance predictions. The company will provide the Advanced EHF payloads to Lockheed Martin, prime contractor for the Advanced EHF system. Test results demonstrated antenna...

Lockheed Martin’s Secure Border Initiative (SBInet) solution will present the Department of Homeland Security (DHS) with a balanced mix of people, process, technology and infrastructure in order to gain full operational control of the country’s borders, the corporation said. The solution was shaped by the company’s eight team members,...

As part of its strategy to further strengthen its UMTS market position and expand its global leadership in broadband access, Alcatel has signed a non-binding Memorandum of Understanding (MoU) with Nortel to acquire its UMTS radio access business (UTRAN) and related assets for $320 M. The acquisition is subject...

To mark its independence from Royal Philips, Philips Semiconductors will move forward as NXP. The name change follows an agreement between Royal Philips and Kohlberg Kravis Roberts & Co. (KKR), Bain Capital, Silver Lake Partners, Apax and AlpInvest Partners NV that will see the consortium take an 80.1 percent...
