xxxW, nnnGHz, ALUMINA Aluminum Oxide POWER CHIP terminationS USM RPTLLLWWWAO-xxxW-nnnGHz FEATURES High power dissipation while working up to 10GHz range frequencies Low insertion loss High reliability and ruggedness Small chip size with reduced stray capacitance per unit area. Low temperature coefficient and wide operating temperature range. APPLICATIONS Applications of Power chip terminations include microwave and RF high power terminations, resistive microwave power dividers, Wilkinson power dividers , power attenuators, microwave power amplifiers. PRODUCT DESCRIPTION AND SHORT APPLICATION NOTE USM RPTLLLWWWAO-xxxW-nnnGHz flange less power chip terminations are designed to be used in chip and wire hybrid circuits as microwave and RF power terminations, power terminations, Wilkinson power dividers, power attenuators, microwave power amplifiers, etc. Flange less thin film power chip terminations and terminations have low temperature coefficients, low noise and increased long term stability compared to their thick film counterpart (see app note 110). In high power applications, temperature coefficient of resistance and long term stability have to be the best available. Suggestions on how to mount and use flange less power chip terminations are available in app note 111. TECHNOLOGY DESCRIPTION: SEMICONDUCTOR-THIN FILM MANUFACTURING All thin film microwave products are manufactured using advanced semiconductors and thin film technologies including ultra-stable and self passivating Tantalum Nitride terminations, gold interconnect metallization and reliable MNOS capacitors to achieve excellent uniformity, performance and reliability. Thin film technology is the preferred solution for all applications that require low noise, long term stability and excellent performance at very high frequencies. US Microwaves employs proprietary thin film technologies for deposition of a wide range of resistive films with sheet resistance films from 1W/sq to 10,000W/sq. All US Microwaves products are available in die form and are ideal for high reliability hybrid and multi chip module applications.
