  • SemiGen PIN Diodes Offer Low Capacitance and Resistance Plus High Reliability

    SemiGen offers PIN diodes that feature low capacitance and resistance, high reliability, and easy bonding with F.A.C. mesas.

    SemiGen's new RF Supply Center provides high-quality PIN diodes that can be shipped or ordered for kits on the SemiGen floor. SemiGen diodes are proprietary, high-quality designs that are fabricated in the United States using a qualified foundry partner.

    The SemiGen SGP7000 series of PIN diodes are processed with a high-resistivity epi that has intrinsic layers, which range in thickness from 4 micron to 200 micron depending on performance specifications. These devices are typically manufactured with either a robust thermal-oxide passivation or ceramic glass for durable high-power applications. These diodes are made with a grown junction P++ layer that yields abrupt junction structures that provide low punch through voltages and minimize autodoping. They are available as chips or in your choice of packages.

    The series includes high-voltage, medium-power/general-purpose, high-power switching and attenuation, ultra-fast switching, and fast-switching/low-power products. Ideal applications are low- to high-power switch, attenuator, duplexer and phase-shifting applications from 2 to 20 GHz.

  • Senator Shaheen and SBA Chief Karen Mills visit Semigen's new Manchester facility

    NH Senator Shaheen and SBA Chief Mills Tour SemiGen Facility

    SemiGen was recently visited by U.S. Senator, Jeanne Shaheen (D-NH), and U.S. Small Business Administration (SBA) chief, Karen Mills, to tour the Manchester, New Hampshire facility and discuss how the SBA program has helped the company develop and grow.

    In 2011, with the help of an SBA 504 loan, SemiGen was able to purchase and fit-out its new Manchester facility. The larger, more fully equipped facility has allowed the contract assembly house, which has a unique specialty in wire bonding and testing of complex microwave circuits, to grow rapidly and add jobs.

    "The SBA provided the efficient financing we needed to expand and create new jobs," said Jim Morgan, President of SemiGen. "Senator Shaheen has been a tremendous advocate in rebuilding our economy and has helped ensure that programs like this stay intact. With the SBA's help, I am thankful to be a part of a group of individuals and businesses creating manufacturing jobs right here in New Hampshire and not overseas."

    The SBA 504 Loan program is an economic development loan program that offers small businesses another avenue for business financing, while promoting business growth and job creation. As of February 15, 2012, the $50 billion in 504 loans has created over 2 million jobs in the U.S.

  • White Paper Discusses Advantages of Keeping Assembly Onshore

    SemiGen has announced that its white paper on contract manufacturing, "The Advantages of Outsourcing Your RF/Microwave Assembly to an Onshore Contractor," is now available for download.

    While the outsourcing of manufacturing occurs across a broad spectrum of industries and offers distinct advantages to OEMs, the outsourcing decision for RF/Microwave (RF/MW) companies involves a unique set of circumstances when compared to conventional digital electronics. For example, RF/MW manufacturing and testing often requires more precisely defined procedures, as well as more precise tools, than digital electronics.

    The SemiGen white paper first details the key advantages offered by outsourcing in general, then discusses the unique circumstances faced by RF/MW manufacturers. The paper makes the case that, due to shifting economic and technological landscapes, outsourcing RF/MW manufacturing overseas no longer delivers the advantages of economy and quality as effectively as onshore outsourcing. The reasons for this, as discussed in the paper, include:

    1. The steadily diminishing cost gap between outsourcing to China and manufacturing in the U.S.
    2. The unique nature of RF manufacturing makes it challenging to transfer the complex RF/MW process to an overseas contract manufacturer with its often-accompanying language difficulties.
    3. Outsourcing to a domestic manufacturer greatly reduces travel expenses on the part of the OEM and eliminates the need to ship U.S.-specific equipment overseas.
    4. Onshore outsourcing significantly lowers the risks of losing proprietary information, a danger inherent when dealing with the limited intellectual property protection offered by developing countries.
