             Taking Performance To a New Peak - 4500B

Boonton has introduced the new 4500B Peak Power Analyzer, which has
been totally redesigned from the inside out. This new instrument is
changing the way the industry views and analyzes RF data. Some of the
key features include: 8.4-inch TFT color LCD display, 100-ps timebase
resolution, automatic peak-to-peak, delay-by-time, and delay-by-events
triggering, and much more.

What Did You Hear At MTT-S?

Last week marked the annual social gathering for the RF/microwave
industry known as the Microwave Theory & Techniques Symposium (MTT-S),
held in San Francisco's Moscone Center. The week-long series of
technical presentations, workshops, and exhibition-booth displays gave
more than 10,000 members of this industry a chance to fill holes in
their professional educations, meet new people, and catch up with old

The show, also known as the International Microwave Symposium (IMS),
serves as a "launching pad" for companies with new product lines. For
a member of the press, there is the inevitable question concerning
"what is new and exciting at this year's MTT-S?" During down economic
times, new product introductions are usually sparse and lackluster.
But, when times are good, product introductions are plentiful. In
terms of exciting new products, this show was a "blockbuster,"
especially in those areas that require considerable capital
investments: semiconductors and test equipment.

A few of the new products related to power (as a way of tweaking
interest for the high-power special report in the upcoming July issue
of Microwaves & RF) are mentioned here, with more exciting new
products to appear in this newsletter as well as in the parent
magazine. And if you feel we have missed yours, please let us know.

Micro-Mode Launches Online Connector Store

Connector specialist Micro-Mode has launched an online store for its
extensive lines of blind-mate and threaded connectors. The company
features SMP, SMPM, and MSSS blind-mate connectors as well as
traditional threaded connectors, such as SMA, SSMA, and TNC
connectors. The company's SMPM connectors are usable from DC to 65 GHz
while the firm's MSSS connectors are suitable for applications from DC
to 75 GHz. Blind-mate connectors can be ordered in a wide range of
configurations, including as cable connectors, printed-circuit-board
(PCB) mount connectors, edge-mount types, bullets, hermetic shrouds,
and surface-mount connectors. Adapters, terminations, and cable
assemblies are also available.

SWTW Honors Cascade's Strid and Gleason

The co-founders of microwave wafer probe supplier Cascade Microtech
have received the prestigious Southwest Test Workshop (SWTW) Lifetime
Achievement Award for more than 25 years of technical contributions to
RF wafer measurements. Eric Strid and Reed Gleason were recognized at
the recent SWTW 2006 (June 11-14, 2006, San Diego, CA), a research
forum sponsored by the Institute of Electrical and Electronics
Engineers (IEEE) Computer Society that focuses on all the aspects
associated with microelectronic wafer and die level testing. Strid,
the company's CEO, said "I'm honored that we have been selected for
this lifetime achievement award, though I feel like we still have
another lifetime worth of ideas to implement." Gleason noted, "Eric
and I will often brainstorm and build on each other's ideas, testing and
challenging each other until we come up with a winner." Strid and
Gleason invented the first 18-GHz wafer probe in 1984. The partners
also created the Pyramid probe card technology, a high-performance
on-wafer solution for testing high-speed, high-density integrated circuits.

RFMD Introduces GaN HEMT Devices

RF Micro Devices (RFMD), a company synonymous with semiconductors for
cellular and other wireless applications, announced a line of gallium
nitride (GaN) high-electron-mobility-transistor (HEMT) power
transistors at last week's MTT-S in San Francisco, CA. Suitable for
both UMTS and WiMAX base stations, the lineup includes models RF3916
with 50 W output power at 2.5 GHz, RF3917 with 75 W output power at
2.5 GHz, RF3918 with 100 W output power at 2.5 GHz, RF3919 with 8 W
output power at 3.5 GHz, and RF3921 with 50 W output power at 3.5 GHz.
According to RFMD co-founder and Chief Technical Officer Bill Pratt,
"For cellular infrastructure and WiMAX base station OEMs dependent on
maximizing power and efficiency, RFMD's GaN transistors provide higher
at-package matching impedance, higher power density, and wide
bandwidth performance when compared with silicon LDMOS devices." The
devices exhibit peak drain efficiencies as high as 67 percent at UMTS
frequencies and 60 percent at WiMAX frequencies.

Smaller TWTAs Deliver 1 kW Power

AR Worldwide RF/Microwave Instrumentation has made a strong statement
that electron tubes are not dead. The firm's latest line of 19-in.
rack-mount traveling-wave-tube amplifiers (TWTAs) are smaller than
standard TWTAs, yet deliver as much as 1000 W output power. The new
line includes the model 511 with 1000 W output power from 2.5 to 7.5
GHz, model 512 with 500 W output power from 7.5 to 18.0 GHz, and model
513 with 1000 W output power from 1.0 to 2.5 GHz.

Freescale Packs Power in 2-GHz Plastic

Freescale Semiconductor introduced 2-GHz high-power RF transistors in
over-molded plastic packages at last week's MTT-S in San Francisco,
CA. Based on the company's seventh-generation LDMOS technology, the
flagship transistor of the new line is the model MRF7S19120N, which is
supplied in a TO-270 WBL-4 package. It provides 120 W peak output
power at 1-dB compression with 36 W average output power at 2.1 GHz.
Typical single-carrier WCDMA performance includes 18 dB gain, 32
percent efficiency, and -37.5 dBc linearity. According to Gavin Woods,
Vice-President and General Manager of Freescale's RF Division,
"Freescale is committed to complementing our air-cavity packaged
devices with cost-effective over-molded plastic models that deliver
exceptional performance." The firm has supplied plastic-packaged power
devices to 1 GHz for several years, now pushing the performance
envelope beyond 2 GHz.
