Ka-band amplifier targets high-volume satellite communications
CML Micro has introduced a Ka-band gallium nitride (GaN) power amplifier designed for commercial high-volume satellite communication terminals. The CMX90A705 is a two-stage GaN linear power amplifier delivering +37.4 dBm (5.5 W) of saturated power, covering a frequency range of 27.5 to 31 GHz and offering 16.5 dB of small signal gain. It can function […]
Capacitors offer high CV, long lifetime, and compact size for high-density designs
KYOCERA AVX released the new RES Series radial-leaded aluminum electrolytic capacitors. The new RES Series wet aluminum electrolytic capacitors are engineered to deliver high CV values in small case sizes, long-lifetime endurance of 5,000–7,000 hours at 105°C, and high ripple current to help manufacturers save board space in high-density PCB assemblies without compromising on endurance. They […]
Fuse line adds 0201 packages, protects 28 mA to 200 mA
KYOCERA AVX extended its Accu-Guard II Low-Current Fuses with new 0201 case sizes that deliver the industry’s lowest current ratings. Accu-Guard II Low-Current Fuses utilize thin-film technology to achieve precise control over the components’ physical and electrical characteristics — beyond what’s possible with standard fuse technologies — and deliver extremely low current ratings in compact […]
DIN rail power supplies series now includes high-power three-phase AC input options
TDK Corporation announces the addition of higher power, three-phase AC input models to the TDK-Lambda DRB series of DIN rail mount power supplies. With 24V, 48V, and 72V outputs, the products are rated for continuous operation at 480W or 960W and can deliver a boost of 720W and 1440W respectively for up to seven seconds. […]
100 V Trench Schottky diodes boost efficiency in high-frequency power converters
STMicroelectronics has introduced 100V trench Schottky rectifier diodes that boost efficiency in power converters operated at high switching frequencies. Raising power-converter operating frequency, encouraged by the minimal switching losses of technologies like wide-bandgap semiconductors, allows designers to set new benchmarks in power density. However, at elevated frequencies, the energy losses in conventional planar diodes, including […]
Industrial ac-dc power supplies meet EMI standards, offer versatile installation options
TDK Corporation announces the introduction of the ZWS-C series of 10, 15, 30, and 50W-rated industrial AC-DC power supplies. The products meet EN55011/EN55032-B conducted and radiated EMI in either a Class I or Class II (double insulated) construction, without the need for external filtering or shielding. With electrolytic capacitor lifetimes of up to 15 years, […]
Rectifiers offer robust ESD protection for automotive applications
Taiwan Semiconductor announces its new line of automotive-qualified rectifiers featuring ESD withstand capability. The new TSD Series rectifiers simultaneously provide repetitive peak reverse voltage (VRRM) of up to 600V as well as ESD protection of >10,000V (per IEC-61000-4-2). Devices in the series have optional current ratings of 1A, 2A, and 3A, and operating temperature ranges from […]
ZVS flyback converter chipset increases efficiency of USB-C adapter, chargers, and travel adapters
The growing popularity of USB-C power delivery (PD) charging increases the demand for compatible chargers. Users now seek powerful yet compact adapters. Infineon Technologies AG addresses this need with the EZ-PD PAG2, a secondary-side controlled ZVS flyback converter chipset. This chipset, comprising EZ-PD PAG2P and EZ-PD PAG2S, integrates USB PD, a synchronous rectifier, and a […]
Modular power EMI filters meet MIL-STD-461
Spectrum Control Inc. introduces a family of modular power EMI filters bringing high performance and design flexibility to a variety of MIL-STD-461 designs with size, weight, power, and cost (SWaP-C) requirements. The chassis mount filters have a wide -55° to 75° C operating temperature. Superior mid- and high-frequency attenuation up to 1 GHz (common mode) is achieved in […]
