Systems, methods, and devices for a ball grid array with non-linear conductive routing are described herein. Systems include a printed circuit board, a microprocessor, a ball grid array, and a substrate. The ball grid array includes a first solder ball and a second solder ball. The substrate includes a non-linear conductive routing electrically coupling the first solder ball and the second solder ball. The non-linear conductive routing includes a first routing section connected to the first solder ball, and a second routing section connected to the second solder ball. The non-linear conductive routing further includes a third routing section connected to the first routing section, and a fourth routing section connected to the third routing section, wherein each of the third routing section and the fourth routing section are rotational routing sections configured to flow current in a first rotational direction.

Compact routing package for high frequency isolation

An example voltage controlled oscillator includes an inductor, a capacitor coupled to the inductor, and a signal source coupled to the inductor and the capacitor to sustain an oscillating signal. The voltage controlled oscillator includes a first varactor coupled to the inductor and the capacitor, wherein the first varactor is biased by a first bias voltage and is configured to change a frequency of the oscillating signal based on a first control voltage signal. The voltage controlled oscillator includes a second varactor coupled to the inductor, the capacitor, and the first varactor, wherein the second varactor is biased by a second bias voltage and is configured to compensate temperature variation of the frequency of the oscillating signal over a plurality of frequency bands based on second control voltage signal.

Oscillator with frequency variation compensation

Systems, methods, and devices for a ball grid array with non-linear conductive routing are described herein. Such a ball grid array may include a plurality of solder balls that are electrically coupled by a non-linear conductive routing. The non-linear conductive routing may include a plurality of routing sections where each of the plurality of routing sections is disposed at an angle to adjacent routing sections.

A two-pin transmit/receive switch design includes a switching component configured to selectively switch in elements for a transmit signal path and elements for a receive signal path. A capacitor in the transmit signal path may be switched out when receiving signals on the receive signal path. Being able to selectively switch out the capacitor allows the capacitor value to be selected for optimal operation during transmit mode. For example, insertion loss may be minimized. In addition, elements in the receive signal path may be optimized (e.g., impedance matching) without being affected by or affecting the optimization that was performed for the transmit signal path.

Two-pin TR switch with switched capacitor

An apparatus for coating a stent comprises a coating solution reservoir, a stent support for carrying a stent adjacent the reservoir, transducers for generating waves through the coating solution, and a controller that controls timing at which the transducers are powered in order to eject a droplet of the coating solution.
