Fairview Microwave Inc. has introduced a new line of relay controlled programmable attenuators that offer accurate and stable performance with very low harmonic distortion (IMD) and cover multiple RF frequency bands down to DC. They are popular for use in military and commercial satellite and ground communication systems, cable modem and cellular telephone testing, radar, […]
Lowest-profile 3216-footprint tantalum capacitor is just 0.5-mm high
AVX Corporation has extended its TACmicrochip Series with the lowest-profile 3216-footprint tantalum capacitor currently available on the market. Measuring just 0.5mm high, the first new “I” case capacitor (EIA Metric 3216-05) is rated for 10μF and 6.3V, but will be followed by future code releases to further extend the offering. The full line of TACmicrochip […]

Waveguide-to-waveguide transitions deliver minimal loss and VSWR as low as 1.08:1
Fairview Microwave Inc., an Infinite Electronics brand, has launched a new line of waveguide transitions that operate from 5.85 to 110 GHz across 14 frequency bands. These waveguide adapters are ideal for high power wireless applications such as test benches, instrumentation, MILCOM, SATCOM, telecom and radar applications where signal strength and integrity are critical. Fairview’s […]
Filters, Part 2: SAW and BAW devices for RF
Part 1 of this FAQ looked at the basic available electronic filters – analog, switched capacitor, and digital – and briefly reviewed the attributes of each. As the frequencies to be filtered reach to 1 GHz and well beyond, while the selectively needed also became narrower, these filter approaches can no longer support many of […]
Isolated analog amps provide accurate current measurements
Silicon Labs has introduced a family of isolated analog amplifiers, voltage sensors and delta-sigma modulator (DSM) devices designed to provide accurate current and voltage measurement with very low drift across temperature. Based on Silicon Labs’ robust, third-generation isolation technology, the new Si89xx family provides flexible voltage, current, output and package options to help developers reduce BOM […]
Filters, Part 1: Analog, switched, and digital filters
Filters are essential functions in most circuits and systems; as frequencies extend into the multi-GHz range, surface acoustic wave (SAW) and bulk acoustic wave (BAW) filters are needed to meet the design objectives. An engineer I worked with (and whose name I have forgotten) once remarked to about electronic filters (and he was serious): “like […]
GPIB port expander enables peripheral I2C interface and level shifting
Diodes Incorporated announced the PI4IOE5V6416 16-bit I/O expander, which enables any digital device to be accessed and controlled over an I2C interface, across a range of input and output voltages from 1.8V to 5V. The PI4IOE5V6416 offers an ultra-low power solution to expanding the available GPIO on a microprocessor, microcontroller, ASSP, ASIC, or FPGA, using […]
Tantalum caps can handle 150°C in industrial/automotive apps
AVX Corporation released a new series of miniature, surface-mount, J-lead tantalum capacitors that deliver high reliability and high volumetric efficiency in high-temperature automotive and industrial applications. The new F9H Series meets AEC-Q200 requirements, is compliant with RoHS2 directive 2011/65/EU, is rated for operating temperatures up to 150°C, and offers the industry’s highest CV/cc in a high-temperature […]
