5. Raytheon to modernize space-based WAAS navigation system
The US Federal Aviation Administration (FAA) has engaged Raytheon to further refine the Wide-Area Augmentation System (WAAS) space-based precision navigation system. Specifically, Raytheon Intelligence & Space will modernize the system, in terms of system security, network architecture and the addition of dual frequency service. WAAS was developed by the Federal Aviation Administration to augment GPS services by increasing its accuracy and availability.

4. Taiwan earthquake leaves little damage to chip factories
Last Saturday night, an earthquake measuring 6.4 on the Richter scale hit Guanshan Township, Taitung, Taiwan, killing one person and injuring three people. Despite a train derailment and the collapse of a bridge and several buildings, no substantial damage was reported to semiconductor fabs, according to TrendForce, and the worst effect at chip factories was been that some machines had to be initialized after a crash. Nanya has already performed a shutdown inspection and, according to TrendForce, if there was damage to the wafers, the company maintains sufficient inventory to compensate.

pickering-4x-724-coaxial-mux-pxi-pxie3. 32 x 8 PXI matrix switch fabrics for RF testing up to 300 MHz
Pickering Interfaces has introduced 32 x 8 PXI RF matrix modules that fit into two chassis slots and offer usable bandwidth up to 300 MHz. Called 40-724 (PXI interface) and 42-724 (PXIe interface), they have a characteristic impedance of 50 Ω and bidirectional signal paths. All X and Y connections have isolation switches to disconnect the matrix from the external test device to maximize isolation and RF performance.

2. Chip expectations vary
Semiconductor Intelligence (SI) has completed its overview of the chip scene. The semiconductor market fell 0.8% in 2Q 2022 compared to 1Q 2022, according to WSTS. The 2Q 2022 decline followed a 0.5% quarter-over-quarter decline in 1Q 2022. 2Q 2022 revenue for the top 15 semiconductor vendors was in line with overall market results, with 1% vs. Q1 2022. Results by company were mixed. Memory vendors SK Hynix and Micron Technology lead with revenue growth of 13.6% and 11.0% respectively in Q2 2022.

1. DRAM collapses
As the DRAM market deflates, a cyclical downturn looms, according to IC Insights. Monthly DRAM sales fall as end users adjust inventory levels and consumer spending succumbs to inflation/recession pressure. A vigorous recovery in the DRAM market that began in the last half of 2020 and continued through May 2022 is, by all accounts, over, according to IC’s Q3 update ​​Insights to the 2022 McClean report.
