GaAs distributed driver amplifier operates from DC – 30 GHz
Custom MMIC has announced the CMD292, a wideband GaAs MMIC distributed driver amplifier die which operates from DC to 30 GHz. The amplifier delivers 13 dB of gain with a corresponding output 1 dB compression point of +27 dBm and output IP3 of 33 dBm at 15 GHz. The CMD292 is a 50 ohm matched […]
12-bit, 29-kHz RGB LED drivers boast 29-kHz dimming frequency
Texas Instruments introduced a new family of LED drivers with integrated, independent color mixing, brightness control and a power-saving mode. The LP5018, LP5024, LP5030 and LP5036 enable smooth, vivid color and reduce system power consumption. The devices are the industry’s first to offer a 29-kHz dimming frequency, above human-audible range, to help designers of applications […]
Common mode choke in 3.8mm (max) package handles currents up to 9 A DC
Pulse Electronics’ Power Business Unit has introduced the PA4339.XXXNLT Small Form Factor Common Mode Choke series for switch mode power supplies. The low profile PA4339.XXXNLT series is the most compact power line common mode choke on the market today that is capable of handling currents up to 9 A DC. The compact design allows for a higher impedance […]
5-W surface-mount current sense shunt runs cool at high power levels
The HCSM2818 is a 5-W surface-mount current-sense shunt with excellent long-term stability and good TCR. The HCSM offers 4 and 5-mΩ values in 200-ppm TCR and 10, 15, and 20 mΩ values in 75-ppm TCR. The molded package and larger terminations provide exceptional thermal resistance and allows the part to run cooler at higher power […]
Capacitors in renewable energy
It pays to know the distinguishing features of electrolytic, film, and super capacitors when planning applications where energy efficiency is important. MORRIE GOLDMAN, ILLINOIS CAPACITOR INC. RENEWABLE ENERGY SYSTEMS all have a common need for high-efficiency power circuits.
