United Monolithic Semiconductors releases new broadband wireless 26, 28 GHz SMD chipsets
Orsay, France. United Monolithic Semiconductors (UMS) is one of the worldwide leaders in design and fabrication of monolithic microwave and mm-wave integrated circuits (MMICs) based on GaAs Technology. To maintain this leadership UMS is always advancing state-of-the-art and setting new trends, which allow the RF-module manufacturers to improve performances and reduce production cost. The latest contribution to this progress is the introduction of Surface Mount Device (SMD) type packaged mm-wave MMICs.
The application of these new products in module fabrication leads to several advantages. First, clean room facilities, high precision pick and place as well as bonding tools can be avoided. Thus, instead of high cost bottleneck tools, well established SMD assembly lines can be used for production of future high-end RF modules. Furthermore, due to substantial pre-testing and the opportunity to repair modules by replacing single SMD type packages, the production yield will increase significantly.
The advantages of the new SMD type packaged MMICs can be best exploited for high volume applications. UMS first focus is on the MMICs designed for applications from 26 to 32GHz range. However, in the near future more chipsets will be available in packaged form, in order to cover lower and higher frequencies.
The first chipset in this frequency band is based on well-known MMICs like CHA2069, CHA2093, CHA3092, CHA2098, CHT3091 which all make use of the high performance P-HEMT processes of UMS. The soft substrate packages used to protect the dies and to allow simpler handling are leadless and can be easily soldered onto a motherboard with a standard pick-and-place process. The additional insertion loss due to the package is typically 1.0dB, which leads to an excellent RF behaviour of the packaged products, close to the performance already known from bare dies.
Many more chipset families will follow and complete UMS products offer soon, as UMS aims to ease its customer s life with advanced and leading edge products. For any further details, please contact our worldwide sales network or visit our website: www.ums-gaas.com
