STMicroelectronics Has New RF Power-MOSFET

High-power radio-frequency devices such as medical scanners and plasma generators will offer improved uptime for owners, as well as increased performance and lower costs, by using the latest generation of high-frequency power transistors offered by STMicroelectronics.

The SD4931 and SD4933 are 150W and 300W N-channel RF power MOSFETs for 50V DC large-signal applications up to 250MHz. The devices deliver the advantages of ST’s enhanced vertical silicon process in a sealed ceramic package with flanges for boalt mounting.

The STAC4932B and STAC4932F utilize ST’s STAC package in bolt-down and flangeless variants, and target 100V pulse applications at power ratings over 1000W. The high thermal and electrical efficiency of the STAC package, which has a thermal base for direct soldering to a heatsink, enables the MOSFETs to produce high signal power at high frequencies while maximizing reliability throughout an extended operating lifetime.

Devices in the ceramic package are already in production and are priced, in quantities of 1000 units, at $43.65 for the SD4931 and $77.60 for the SD4933. The STAC4932B and the STAC4932F devices in the STAC package are priced at $67.90. Alternative pricing options are available for larger quantities.

Combined EMI Filtering, ESD Protection

ON Semiconductor has introduced a new range of common mode filter (CMF) devices with integrated electrostatic discharge (ESD) protection to suppress noise and provide strong signal integrity. The new EMI2121, EMI4182 and EMI4183 devices are highly suitable for implementation in smartphones, media tablets, wireless connectivity dongles and digital camcorders, as well as set top boxes and DVD players.

The new CMFs are silicon making them better suited to suppress EMI to deeper levels and at higher frequencies than ceramics or ferrite based solutions. Integrating ESD protection with EMI suppression offers space savings of up to 50% which translates into significant bill-of-materials savings. handset designers.

The EMI2121 single pair CMF, EMI4182 dual pair CMF and EMI4183 triple pair CMF all offer a common mode rejection of 15dB (typical) at 500MHz and an insertion loss of only 1.0dB (typical) at 500MHz. Their high differential mode bandwidth cutoff frequency ensures high levels of signal integrity.

RF Tool for Positive Train Control Networks

EDX Wireless has released EDX SignalRail, a flexible RF planning solution that incorporates advanced route-based studies specifically designed for planning positive train control (PTC) wireless networks, yet with broad application to other route-based transportation wireless network applications.

PTC RF links are designed primarily for communication and control along a rail line, making the radio coverage and interference off the tracks less relevant to PTC operation. The EDX SignalRail network design module incorporates several innovations in RF planning which simplify and improve the design and planning of RF networks for PTC systems. Based on the latest version of EDX SignalPro suite of RF planning tools, SignalRail concentrates calculations along the rail lines creating a high-resolution study that can be run more efficiently and quickly than a comparable study using conventional planning tools.
