In brief: JDSU, Skyworks, Rohm and Haas, RFMD

JDSU's higher-power 980 nm pump lasers get qualified for submarine applications, Skyworks looks to extend its power amplifier applications base in a deal with Motorola, Rohm and Haas Electronic Materials develops a novel, less-toxic precursor for germanium epitaxy, and RF Micro Devices ships its 10 millionth Polaris transceiver.

JDSU's new lasers get qualified
Diode laser manufacturer JDSU says that its latest high-power 980 nm laser pump modules have been qualified for undersea telecommunications applications.

The San Jose, CA, outfit produces the majority of the world's 980 nm pumps, which are used to boost optical signals as they carry voice and data traffic across the world.

According to the company, the 400 mW laser modules exceed the Telcordia standards that define the operational requirements for optical telecommunications components, and should now be deployed as long-haul and ultra-long-haul networks are upgraded to cope with demand for broadband services.

The Series 5000 module is said to double the power of previous-generation pump modules.

Skyworks and Motorola to extend PA application
Power amplifier (PA) and RFIC manufacturer Skyworks Solutions is working with Motorola in a development that should extend the relationship between the two companies beyond cell-phone handsets.

The Woburn, MA, maker of GaAs-based chips says that it has signed an exclusive agreement with Motorola to jointly develop Terrestrial Trunked (TETRA)-based PAs.

The custom design will then be used by Motorola in two-way radio platforms destined for use in public safety and security applications.

TETRA is Europe's open digital RF standard, which has also been adopted in Asia and South America.

Rohm and Haas precursor suggests safer Ge epitaxy
Metalorganics specialist Rohm and Haas Electronic Materials (RHEM) has developed a new precursor for germanium that could result in safer growth of high-purity films based on the material.

The new chemical, known as iso-butyl germane, is a liquid precursor with a high vapor pressure that is less toxic than regular germane.

According to RHEM, it could benefit manufacturers of triple-junction solar cells. This is because the solar cell performance can be compromised by a germanium memory effect that originates at the epitaxy stage in the manufacturing process.

RFMD passes transceiver milestone
GaAs HBT producer RF Micro Devices says that it has now sold over 10 million of its Polaris cellular transceivers.

The Greensboro, NC, company attributes the success to strong sales of its EDGE transceivers for high-end cell-phone handsets.
