PART II. OTHER INFORMATION
 
 Item 1. Legal Proceedings
   
 Item 1A. Risk Factors
 You should consider carefully the following risk factors as well as other information in this
report before investing in any of our securities. If any of the following risks actually occur, our
business, operating results and financial condition could be adversely affected. This could cause
the market price of our common stock to decline, and you may lose all or part of your investment.
 **
    
    Indicates risk factor has been updated since our Annual Report onForm 10-Kfor
the year ended December 31, 2005.
 Risks Relating to Our Business
 We have had a history of losses and may not be profitable in the future. **
  We depend on a small number of key customers in the telecommunications industry for a large portion
of our revenues. If we lose any of our major customers, particularly Nera, Nokia or Siemens or
there is any material reduction in orders for our products from any of these customers, our
business, financial condition and results of operations would be adversely affected. **
  20

##### Table of Contents



We depend on the telecommunications industry for most of our revenues. If this industry suffers
another downturn or fails to grow as anticipated, our revenues could decrease and our profitability
could suffer. In
addition, consolidation in this industry could result in delays or cancellations of orders for our
products, adversely impacting our results of operations.**
    Our future success depends in part on our ability to further penetrate into new markets, such as
defense electronics and homeland security, and we may be unable to do so.
  Our operating results may fluctuate significantly based on seasonal factors in the
telecommunication network market. **

##### Table of Contents



Because of the shortages of some components and our dependence on single source suppliers and
custom components, we may be unable to obtain an adequate supply of components of sufficient
quality in a timely fashion, or we may be required to pay higher prices or to purchase components
of lesser quality.

We rely heavily on a Thailand facility of HANA Microelectronics Co., Ltd., a contract manufacturer,
to produce our RF modules. If HANA is unable to produce these modules in sufficient quantities or
with adequate quality,
or it chooses to terminate our manufacturing arrangement, we will be forced to find an alternative
manufacturer and may not be able to fulfill our production commitments to our customers, which
could cause sales to be delayed or lost and could harm our reputation.
  We rely on Velocium and other third-party semiconductor foundries to manufacture the semiconductors
contained in our products. The loss of our relationship with any of these foundries, particularly
Velocium, without adequate notice would adversely impact our ability to fill customer orders and
could damage our customer relationships.**
   Implementing our acquisition strategy could result in dilution to our stockholders and operating
difficulties leading to a decline in revenues and operating profit.

   Our products may contain component, manufacturing or design defects or may not meet our customers
performance criteria, which could cause us to incur significant repair expenses, harm our customer
relationships and industry reputation, and reduce our revenues and profitability.**
   We depend on our key personnel. Skilled personnel in our industry can be in short supply. If we are
unable to retain our current personnel or hire additional qualified personnel, our ability to
develop and successfully market our products would be harmed.

##### Table of Contents



Competitive conditions may require us to reduce prices in the future and, as a result, we may need
to reduce our costs in order to be profitable.**
  The length of our sales cycle requires us to invest substantial financial and technical resources
in a potential sale before we know whether the sale will occur. There is no guarantee that the sale
will ever occur and if we are unsuccessful in designing a high-frequency RF module for a particular
generation of a customers products, we may need to wait until the next generation of that product
to sell our products to that particular customer.
  We may not be able to design our products as quickly as our customers require, which could cause us
to lose sales and may harm our reputation.

We may not be able to manufacture and deliver our products as quickly as our customers require,
which could cause us to lose sales and would harm our reputation.

    political instability.

##### Table of Contents



Because we do not have long-term commitments from many of our customers, we must estimate customer
demand, and errors in our estimates could have negative effects on our inventory levels, revenues
and results of operations.
  Some of our customer contracts require us to manufacture products designed by our customers. While
we intend to convert many of these products to products of our own design, such transitions may be
difficult and/or expensive to implement and delays or difficulties in doing so could harm our
operating results.
  Any failure to protect our intellectual property appropriately could reduce or eliminate any
competitive advantage we have.**

Risks Relating to Our Industry
 We have increased the volume of our products used by the United States government. Our revenues in
this market largely depend upon the funding and implementation decisions of Congress and United
States government agencies. These decisions could change abruptly and without notice, unexpectedly
reducing our current or future revenues in this market.
  Our failure to compete effectively could reduce our revenues and margins.

##### Table of Contents



Our failure to comply with any applicable environmental regulations could result in a range of
consequences, including fines, suspension of production, excess inventory, sales limitations and
criminal and civil liabilities.
  Government regulation of the communications industry could limit the growth of the markets that we
serve or could require costly alterations of our current or future products.
  Risks Relating to Ownership of Our Stock
 The assets of Wood River Capital Management, LLC and certain of its affiliates, the holders of
shares of common stock representing approximately 26.2% of our outstanding capital stock as of
