摘要:
A patch antenna array is fabricated with a package-on-package setup that contains a transceiver. The patch antenna array has a footprint that intersects the transceiver footprint. The package-on-package setup includes through-mold vias that couple to a redistribution layer disposed between the patch antennas and the package-on-package setup.

Techniques and configurations are disclosed for bulk acoustic wave resonator (BAWR) tuner circuits and their use in integrated circuit (IC) packages and mobile communication devices for radio frequency (RF) communication. In some embodiments, a mobile communication device may include an antenna; a transmitter circuit having an output port, a tuner circuit having one or more BAWRs, an antenna port coupled to the antenna, a transmitter port coupled to the output port of the transmitter circuit, and a control port; and a control circuit, coupled to the control port, configured to adjust an impedance of the tuner circuit, via adjustment of a BAWR or another component of the tuner circuit, based at least in part on an impedance of the antenna. Other embodiments may be described and/or claimed.
摘要:
The present invention discloses methods for the synthesis of oligonuclelotidesa and nucleoside phosphoramidites. The methods are based on employing aryl-substituted 5-phenyl-lH-tetrazoles with perfluroalkyl groups on the aromatic ring as activators. In one aspect the activators are used in the synthesis of oligonucleoties via the phosphoramidite approach. In this aspect the activators are highly efficient and can be applied with very short coupling times. In a further aspect, the activators of the invention are used in the synthesis of phosphoramidites through the reaction of nucleosides comprising a free hydroxyl group with phosphitylating agents. This aspect of the activators provide very pure phosphoramidites under mild conditions. The activators of the invention are further characterized as being highly soluble, non-hygroscopic and non-hazardous.
