While microwave and millimeter-wave high-power vacuum electron devices (VED) remain “below the radar” of many industry observers, the total available market (TAM) for this segment is nearly $1 B. Despite its size, and although these tubes (valves) remain essential elements in specialized military, scientific/medical and space communications applications, this...

As mobile network expansion moves ostensibly to emerging markets where solar energy levels are more favorable, solar power appears ready to play an important role in reducing the costs of cellular service delivery and ensuring a more reliable power supply. The OEMs’ drive toward reducing base station power consumption,...

Industry News EMS Technologies Inc. announced that it has signed a definitive agreement to acquire Satamatics Global Ltd. , a global provider of Inmarsat IsatM2M (machine-to-machine or “M2M”) services, headquartered in Tewkesbury, UK. The acquisition complements the company’s existing Iridium- and Inmarsat-based tracking solutions. EMS expects the acquisition to...

Nowadays, microwave antennas are widely used, especially in achieving the objective of maximal integration for personal communication systems. These antennas can be mounted on the surface of high performance aircrafts, satellites, missiles, mobile phones and others. Integrated antennas are a combination of solid-state devices and circuits with printed antenna...

Linear antennas and their many variations have been essential to wireless communication and sensing for over a century. They have been widely deployed over the electromagnetic spectrum, especially at wavelengths ranging from VLF through microwaves. Even though they have been intensely studied throughout that time, there remain some fundamental...

High power RF amplifiers are expected to provide high primary performance parameters such as output power, gain and efficiency, as well as operate reliably for more than 20 years in the field. Traditionally, designers have built these amplifiers using components fabricated in cost-effective silicon-based technologies such as bipolar or...

There are a number of applications and uses for the 4.4 to 4.99 GHz band. These include the 4.4 to 4.5 GHz band, which is designated in the US and NATO countries for military fixed and mobile communications. Typical uses include point-to-point microwave links and telemetry applications such as...

When testing an antenna, the test engineer must typically measure a number of parameters such as the radiation pattern, gain, impedance, or polarization characteristics. One of the techniques used to measure antenna patterns is the far-field range where an antenna under test (AUT) is placed in the far-field of...

Silicon RF and microwave power transistors have been supporting long-range surveillance radar systems since the early 1970s, starting at UHF with peak powers of 100 W at ~50 μs, 20 percent duty for the first UHF radar and L-band with peak powers of about 50 W at 100 μs,...

Technical Overview This new technical overview explains the performance capabilities of the Agilent N9360A mobile station tester, which is a multi-format economy test platform with just enough go/no go test capabilities to meet the needs of the low cost mobile station test market. The free technical overview, “Agilent N9360A...
