PRODUCT DESCRIPTION AND SHORT APPLICATION NOTE
The USM RG1020T20 series of 20GHz microwave thin film chip resistors is designed to be used in microwave hybrid circuits for biasing of active components and as feedback resistors for high speed transimpedance amplifiers for optical communication receivers. To attain very low capacitance to ground, these chip resistors are manufactured on 20 mils Al2O3 ceramic substrates and do not have backside metallization.
These devices are specifically designed and manufactured to be compatible with gold wire bonding. These devices can be used over the full military temperature range -55°C to +125°C. Quality and workmanship is per MIL-S-883. Devices are 100% tested, visual inspected and packaged in waffle packs. US Microwaves employs proprietary thin film technologies for deposition of a wide range of sheet resistance films from 1W/sq to 10,000W/sq.
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 resistors, 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.
