FLIP CHIP RESISTORS - MICROWAVE THIN FILM CHIP RESISTORS for f>20GHz APPLICATIONS -20GHz - thin film resistors for microwave and transimpedance amplifiers for optical communication receivers RG1020-xx-FC The RG1020-xx-FC series of 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 10 mils Al2O3ceramic substrates and do not have backside metallization. In addition of the regular RG1020-xx series, RG1020-xx-FC has a protective dielectric coating that prevents shorting due to the conductive epoxy.These devices are specifically designed and manufactured to be compatible with flip chip conductive epoxy mounting.
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 10,000 W/sq.Custom
lab kits are available: RG Lab kit.The resistive material is high stability Tantalum Nitride with low temperature coefficient of resistance, <75ppm/°C typical. For Rsq<10W/sq and Rsq>500W/sq, the resistive material is proprietary.The bonding pads of the
resistors are 3mm 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 NOT metallized. Standard TiW/Au or other custom metallizations are available upon special request.US MICROWAVES,

Company's technology road map is including SiGe epi devices for high speed RF bipolars and high speed fiber
optic and optoelectronic applications. Analog devices, ASIC analog design and manufacturing: Semiconix produces a series of semi-custom bipolar analog devices in arrays that are customized by designing a specific metal interconnection mask. The arrays contain a large number of undedicated active and passive components, i.e. transistors, diodes, resistors, capacitors, MOSFET s, LDMOS, photodiodes, phototransistors, etc. Since wafers are stocked before the metal mask, the custom IC development phase
is shorter and far less expensive compared to conventional full custom ICs. Customers may provide own analog design. Optoelectronic components: photodiodes, photodiodes arrays, phototransistors, position sensing devices, optocouplers, optoisolators, photodarlington, high voltage phototransistors output, Schottky infrared detectors.
