REMEC Magnum introduces SectorShape antennas for LMDS hubs. Designed using a highly automated process that takes advantage of advanced EM analysis and artificial intelligence

A photoengraveable silver conductor paste, designated KQ610, produces high-density interconnections

The ADRF5474 is a 4-bit digital attenuator with 22 dB attenuation control range in 2 dB steps manufactured in a silicon process attached on a gallium arsenide (GaAs) carrier substrate. The substrate incorporates the bond pads for chip and wire assembly, and the bottom of the device is metalized and connected to ground.

The SKY66186-11 is a high-linearity lower amplifier designed for FDD 3G/4G LTE small cell base stations that operate within the 728 – 768 MHz frequency range. It is also useful for active distributed antenna systems, cellular repeaters, and driver amplifiers. The amplifier features a fully matched input/output, high gain, and an active biasing circuitry that is integrated to compensate its performance over temperature, voltage, and process variation.

The SKY87000-13 is the new step-down regulator from Skyworks with an auto-bypass LDO designed to dynamically control the operating voltage of multi-band, multi-mode WCDMA or GSM/EDGE power amplifiers. The regulator has an output voltage between 0.40 and 4.25 V that is controlled by an analog signal from the baseband processor, and provides the optimum efficiency for all operating states.

Aluminum driers are effective as through driers. They function as crosslinking agents becoming an intimate part of the dried film.

The image above shows a PCB that Standard Printed Circuits custom manufactured for the industrial controls industry. Proper laminates for the innerlayer manufacture were pulled first, followed by the drilling of tooling holes in the panels and then moved to the imaging department. The custom design was then transferred to the innerlayer panels through the use of different Photolithographic methods, then subjected to a thorough in-process inspection. Unwanted copper was then removed through the use of chemicals in the etching department, followed by another in-process inspection.

The 0405-1000M transistor from Microsemi Power Products Group is designed for UHF frequency, 400 to 450 MHz. This high performance, common emitter, class C, output stage offers unparalleled performance of 1000W of peak power, 70% collector efficiency at 450 MHz, and is in a hermetically sealed package for the best reliability for weather radar and over the horizon radar applications...
