In high power applications, temperature coefficient of resistance and long term stability have to be the best available. 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 1Ω/sq to 10,000Ω/sq. All US Microwaves products are available in die form and are ideal for high reliability hybrid and multi chip module applications. All US Microwaves products are manufactured using GOLD CHIP TECHNOLOGY™ a trade mark of Semiconix Corporation.

ONLY Proper die handling equipment and procedures should be employed. Stresses beyond listed absolute maximum ratings may cause permanent damage to the device. GENERAL DIE INFORMATION Substrate Thickness [mils] Size [mils] Bonding Pads Backside metal Beryllium Oxide (BeO) 40±0.5 40x20±2 The bonding pads of the resistors are 3µm thick, 99.99% electroplated gold with a TiW barrier that withstands 30 min at 400°C in air without loss of adhesion. The backside of the die is metallized with TiW/Au which is compatible with most die attaching methods. Other metallizations are available upon special request. All US Microwaves products are available in die form. Typical delivery for die products is 2-3 weeks ARO. For Custom designs, delivery is 3-4 weeks ARO. Certain items may be available from stock. Inventory is periodically updated. All devices for chip and wire applications are 100% tested, visual inspected and shipped in waffle packs (WP). Thin Film Power Resistor Divider 2-Way DIE LAYOUT / MECHANICAL SPECIFICATIONS 4.7Ω, 145.06GHz, 10W BERYLLIUM OXIDE POWER CHIP RESISTOR DIVIDER USMRPD2040BO40-4R7 Thin Film Power Resistor Divider 2-Way CHIP MOUNT 4.7Ω, 145.06GHz, 10W BERYLLIUM OXIDE POWER CHIP RESISTOR DIVIDER USMRPD2040BO40-4R7 power chip resistor mount Thin Film Power Resistor Divider 2-Way ASSEMBLY PROCESS - SHORT APPLICATION NOTE Power chip resistor dividers are designed for critical designs where space is at premium. The power chip resistor dividers can be die attached to the heat sink or to a base plate using AuSn or AuGe preforms. Since the power chip resistor dividers do not have terminals, they have to be attached using gold ribbon via gap welding after the backside is soldered in place. Backside metallization for power chip resistor dividers is Ti/Pt/Au which is also compatible with Sn solder. For the more common SnPb, a Ti/Ni/Au backside metallization should be requested.
