           Programmable Power for RF Amplifiers from Lambda 

Genesys(TM) AC/DC 1U and 2U rack-mount power supplies give flexible, 
reliable power in space-saving 1U and 2U packages. These supplies 
offer outputs to 600 VDC and 400 A. Worldwide inputs, Active PFC, and 
RS-232/485 interfaces are standard.  Full set of user-friendly control 
features. New option IEMD controls up to 31 slaves over RS-485 instead 
of GPIB Card in each supply. New Advanced Parallel function allows up 
to four to act as one for power up to 13.2 kW.

There's Always Room For One More

The microwave industry can safely be called a "mature" industry, with 
many businesses exceeding 50-year lifetimes. This magazine itself will 
be celebrating its 45th year of operation. In all that time, one might 
think that the number of competitors in a given part of the microwave 
marketplace would diminish or at least remain stable. But in this 
newsletter, for example, several new companies (Keragis Corp. and 
PrecisionWave Corp.) have announced offerings in their respective 
parts of the industry, broadband amplifiers and test equipment.

This industry has grown and matured because of this entrepreneurial 
spirit and the willingness of clever engineers with good ideas to take 
a chance on a new business. Sometimes they have invested with their 
own funds, sometimes with help from a bank or investors, but the risk 
of starting a company is always great. And the industry has always 
shown that it can support good products and good ideas, no matter how 
many suppliers were competing previously in that space. For a good 
microwave engineer, there's always room for one more company.

Precision Wave Builds Cellular Signal Generator

PrecisionWave Corp. entered the RF test market with their model p1211B 
RF signal generator for cellular testing. With 1-Hz frequency 
resolution from 800 to 1000 MHz and 1700 to 2200 MHz, the generator 
can settle within 100 Hz of a new frequency in 1 ms when operating in 
command list mode. The generator provides output levels from -100 to 
+20 dBm with 0.1-dB resolution. The accurate, low-noise source (phase 
noise of just -115 dBc/Hz offset 100 kHz from the carrier) provides 
high modulation accuracy for a variety of cellular standards, 
including GSM, EDGE, MACS, PHS, and WCDMA.

Keragis Offers Solid-State TWTA Replacement

Keragis Corporation has designed a patent-pending solid-state, 
high-power traveling-wave-tube (TWT) replacement module capable of 
providing 35 W output power from 6 to 18 GHz. Weighing a mere 0.5 lb., 
the model KHPA-0618-35W amplifier module features 20-dB typical gain 
while drawing 11 A current from an +8-VDC supply. The design employs 
numerous monolithic microwave integrated circuits (MMICs) and discrete 
devices to minimize single-point failures. The reliable, 
patent-pending design approach eliminates the "zipper effect" by which 
failures of one device in some amplifiers can cause the failure of all

NoiseWave Launches Instrument Noise Generator

Noise specialist NoiseWave has announced the availability of its 
NW3G-MINoise Instrument with broadband frequency coverage from 10 MHz 
to 3 GHz. It delivers 0 dBm output power with output flatness of +/- 
2.5 dB. It is available in a half-rack enclosure or in a tabletop 
version and is ideally suited for wireless component and system 
testing, bit-error-rate (BER) testing, signal simulation, and 
cable-television (CATV) testing. Other output levels and frequency 
ranges are also available.

HFET Hits 0.3-dB NF At 12 GHz

California Eastern Laboratories has introduced a heterojunction 
field-effect transistor (HFET) that helps eliminate noise and improve 
sensitivity in microwave receivers. Ideal for X-band and Ku-band 
applications, the model NE3511S02 transistor achieves a noise figure 
of 0.3 dB at 12 GHz with associated gain of 13.5 dB (running from a 10 
mA, 2-V supply). The transistor is housed in a lead-free, plastic 
surface-mount package measuring just 3.2 x 3.2 mm with recessed leads.

BAW Duplexers Filter Cellular Phones

EPCOS has begun volume shipments of its B7633 series 
bulk-acoustic-wave (BAW) duplexers to a leading domestic US 
manufacturer of mobile telephones. The BAW duplexers provide the 
power-handling capabilities of ceramic filters with the small size of 
surface-acoustic-wave (SAW) filters. They measure 5 x 5 mm with a 
height of 1.35 mm. Suitable for US PCS and WCDMA band II applications, 
the duplexers exhibit insertion loss of 3.6 dB in the receive band and 
2.7 dB in the transmit band with good receive-transmit band isolation 
of as high as 57 dB.

VCom Adds Broadband Wireless Technologies

Last-mile access technology supplier VCom, Inc. has completed an 
agreement with Wave Wireless Corp. to acquire a cluster of companies 
that will provide new broadband wireless technologies, synergistic 
sales channels, and substantial revenues in product sales. Under the 
terms of the agreement, VCom has purchased WaveRider Communications 
(Canada) Inc., WaveRider Communications (USA) Inc., Jetstream Internet 
Services Inc., and Avendo Wireless Inc. from their parent WaveRider 
Communications Inc, a subsidiary of Wave Wireless Corp. The shares of 
all the companies will be purchased for approximately $1 million US 
dollars, to be paid in cash. As part of the acquisition, VCom has 
entered into a supply agreement with Wave Wireless pursuant to which 
VCom will produce under license the 900 MHz product portfolios 
marketed by Wave Wireless. The companies also intend to sell each 
other's wireless product portfolios. VCom's best-in-class series of 
point-to-multipoint products in the 700 MHz, 1.9 GHz, 2.5 GHz, 3.5 GHz 
and 5.8 GHz bands as well as its burgeoning WiMAX product line will be 
marketed by Wave Wireless to its established customer base.
