Boonton announces the launch of the first two members of a new USB Power
Meters series: the 52012 and 52018.
Extending its product portfolio with the
52000 series family, Boonton is now providing reliable entry level USB
controlled CW Power Meters. The new meters offer a frequency range from 10.0
MHz to 12.4 / 18.5 GHz and allow accurate power measurements between -50
dBm to + 20dBm. Its VSWR is better than 1:1.25 at 50 Ohms impedance.
WiMAX supporters hoping for the marriage between Sprint and Clearwire were clearly
disappointed earlier this month when the two companies were unable to come to terms
on a WiMAX partnership. The two firms had hoped to create a nationwide WiMAX
operation that would cover both large metropolitan and mid-sized markets in the United
States. Unfortunately, Sprint's recent poor financial performance turned into a
stumbling block for the WiMAX joint venture, although representatives from both
companies have not ruled out the possibility of the two communications service
providers teaming on some form of a WiMAX partnership in the future.
In spite of this "speed bump," the growth of mobile WiMAX appears inevitable. Given
the appetite in this country for Internet web browsing, and the desire for mobility,
devices such as WiMAX-enabled cellular telephones will provide broadband Internet
access anywhere within a WiMAX network. Information on WiMAX is plentiful, with
industry companies invited to visit the WiMAX Forum (www.wimaxforum.org) or
WiMAX.com (www.wimax.com) for more information. In addition, the IEEE
(www.ieee.org) is offering a Webcast on December 5th, "WiMAX: Ready for Prime
Time," moderated by former Wireless Systems Design Editor, Ron Schneiderman. As
with Bluetooth and WLAN wireless technologies before it, considerable industry
firepower supports fixed and mobile WiMAX, making it a good bet for future success.

Phase Matrix has won a $700,000 contract from Lockheed Martin Systems Integration-
Oswego to develop an X/Ku-band digitally tuned oscillator (DTO) for the United States
Air Force's B-2 stealth bomber. Integration of the DTO is part of the modernization of
the B-2's electronic systems. The DTO design is based on low-phase-noise, fast-tuning
voltage-controlled oscillators (VCOs) that are digitally linearized for excellent frequency
accuracy with low drift over temperature and across the tuning range. According to
noted oscillator designer Dr. Paul Khanna, Vice-President of Phase Matrix, "This
contract fully reflects Lockheed Martin's confidence in our company and in the ability
of our Components Group to meet the challenging requirements of a critical component
for the B-2 bomber." Khanna added that the contract "also affirms our capabilities in
the field of complex microwave subassemblies."
Phase Matrix's Components Group offers extensive lines of products from 1 to 50 GHz
for instrumentation, military, and telecommunications applications, including fixed-
frequency and phase-locked oscillators. The company's custom subassemblies are
based on a wide range of analog and digital functions, including integration of switches,
oscillators, filters, attenuators, frequency conversion, power supplies, microprocessors,
and memory.
Tyco Electronics Corp. has announced a new line of RoHS-compliant RF coaxial
connectors for a variety of applications, including test and measurement equipment,
industrial process and control equipment, and medical equipment. The ZDC family of
connectors are based on die-cast components and thermoplastic dielectric materials.
They are designed with a bayonet coupling mechanism for applications requiring rapid
connectivity and threaded coupling for applications requiring secure terminations. Initial
models are available in BNC interfaces and a range of cable-mounted plugs and jacks as
well as bulkhead and printed-circuit-board (PCB) sockets. Connectors can be supplied
for 50 and 75 ohm systems at operating frequencies from DC to 40 GHz. The ZDC
connectors meet MIL-C-39012 and MIL-STD-348A requirements.
Whether it’s an amplifier, attenuator, filter, mixer, or switch, or any other
RF/microwave component, or printed-circuit board (PCB), or transistor, or software, or
test equipment, you'll find a source in the Microwaves & RF Product Data Directory.
