Hi-Rel RF/Microwave Product Solutions

 

A growing archive of some of the best RF/Microwave semiconductor solutions available

From low-cost, GaAs MMIC components to high-power switches on aluminum nitride, KCB has the experience you need to develop the optimal solution for your design. As an experienced designer of GaAs, Si, and GaN semiconductor products, KCB has created a vast archive of standard and semi-standard, Hi-Rel solutions. KCB's high-reliability products, or variants thereof, are available with faster turnaround times, and limited to zero NRE. The products below represent a sample from each product group. Datasheets can be viewed by clicking on a model number. The devices below are supplied in accordance with the 100% screening requirements of MIL-PRF-38535, Class B/S and MIL-PRF-38534 Class H. These devices can also be supplied against the requirements of Class S or without screening.


Hi-Rel Without the High Price or the Long Lead Time

 Changing the notion that Hi-Rel is expensive and only available with long delivery times, KCB is pleased to offer a new line of screened components attractively priced and with reduced lead times. These GaAs devices meet the screening and qualification requirements of MIL-PRF-38534 and MIL-PRF-38535 and are available in your choice of leaded packages or newly qualified KCB hermetic QFNs. They're ideal for all your military and space requirements. 

GaAs SPST Switch, SPDT Switch, and SP4T Switch
The KCB Hi-Rel line of broadband pHEMT GaAs FET switches range from DC - 6 GHz and offer isolations as high as 56 dB and losses as low as 0.5 dB.

Broadband GaAs Digital Attenuator
KCB Hi-Rel digital attenuators range from DC - 6 GHz and feature a GaAs broadband seven-bit pHEMT digital attenuator. They deliver low insertion loss of 1.8 dB, excellent attenuation accuracy of +/- 0.15 dB, and an attenuation range of 31.75 dB. Integrated into the device is a TTL/CMOS-compatible, dual-mode serial or parallel-programming interface controller.

Wideband GaAs Power Amplifier
KCB810 is a Hi-Rel GaAs pHEMT high performance, ultra-wideband 0.4 - 2.7 GHz power amplifier offering superior output power, low noise, high linearity, and high efficiency.

New DC to 6 GHz Switch Offers High Power Design Flexibility

 KCB's latest SPST through SP6T switches are ready for your high power-handling requirements from 20 to 200 Watts. These versatile devices feature the highest power-handling capability available in standard QFN packages and themally conductive flange-mount packages. As an added feature, they're shipped complete in your choice of multiple factory-configured ports. 

Designed and manufactured with PIN diode technology, they're 100 percent RF tested (small signal), have robust carrier construction, and are composed with thick deposition thin film traces. They're housed in standard 5 or 7mm QFN-style packages, high power flange packages and also in hermetic packages. They've been created for applications where robust design/construction and low costs are key application drivers.
