Low-cost RF sniffer finds 2.4-GHz sources
27.11.2017 · Circuits
Whether you measure or use RF circuits that operate in the popular 2.4-GHz ISM band, cordless telephones, Wi-Fi access points, Bluetooth devices, and microwave ovens can radiate RF signals, causing unwanted interference. A spectrum analyzer remains the instrument of choice for detecting and identifying interference sources, but analyzers are expensive, bulky, and sometimes not readily available...
Analog Devices Announces Active Rectifier Controller with Reverse Protection
27.11.2017 · News
Analog Devices announces the Power by Linear LT8672, an active rectifier controller with reverse input protection to –40 V. Its 3 V to 42 V input voltage capability is ideal for automotive applications which must regulate through cold-crank and stop-start scenarios with minimum input voltages as low as 3.0 V and load dump transients up to 40 V...
Low-dropout regulator, SMPS cascade suppress ripple, maintain efficiency
25.11.2017 · Circuits
A step-down SMPS efficiently converts unregulated power to a regulated output voltage. However, unwanted switching-induced ripple and input transients may appear on the output. Applying noisy power to an RF power amplifier can inject spurious signals or modulated noise into the broadcast spectrum...
