AtlantecRF , the UK-based microwave components and equipment manufacturer, considers that its new amplifier could possibly be the most versatile in the world in that it is capable of operating over a temperature range from -269°C (4K) to +100°C at frequencies from 1 to 20 GHz. Model AOX-010200 is...

Microwave power devices have recently played an important role in wireless communication systems, in which both the output power density and the device linearity are key factors in increasing the dynamic range, while satisfying the linearity requirements. The electric field profile across the channel of a PHEMT is a...

Ultra-wideband (UWB) technology has been a key issue in the development of new high speed indoor and hand-held wireless communication systems since the unlicensed use of UWB was approved worldwide. As one of the essential components in UWB communication systems, the UWB bandpass filter (BPF), with such characteristics as...

There has recently been an exponential growth in worldwide wireless communications. The IEEE 802.11 group has been responsible for setting up standards, including those for wireless local area networks (WLAN), and dual-band communication at 2.4 GHz (2400 to 2483.5 MHz) and 5.2 GHz/5.8 GHz (5150 to 5350 MHz and...

Commercially available RF, microwave and optical driver amplifiers provide their best performance under specific bias conditions. The quiescent current of such amplifiers affects critical performance parameters such as efficiency, inter-modulation distortion products and noise figure. Therefore, it is crucial to bias these amplifiers accurately for best performance. Some amplifier...

The increasing content of today's smartphones dictates shrinking form factors and increased flexibility in the RF Front-End (RFFE). Mainstream cellular devices support two bands of W-CDMA for home network data access and four bands of GSM/GPRS/EDGE for worldwide mobility. Focus on cost has driven the industry to reuse the...

RFCONNEXT Inc. has developed a family of advanced high speed, wideband transmission lines, comprising patent pending PMTL™, VMTL™ and SMTL™, that provide new possibilities for cables and connectors, high speed PCB routing, electronic packaging interconnects, test and measurement probing, and RF/microwave and wireless communication applications. These advanced transmission lines...

Anaren Inc. has officially launched its Xinger®-III brand family of 3 dB hybrid and directional couplers for wireless infrastructure applications. The two new passive devices offer improved power handling, lower loss and other electrical performance metrics of interest at only ¼ the size of the company's previous-generation Xinger-II components...

With cell phone makers ready to transition to the Long-Term Evolution (LTE) standard later this year, designers require advanced transceiver technology that supports a broad range of industry basebands including 2G and 3G, in addition to LTE. Designers also need an efficient, compact, highly integrated transceiver to reduce total...

RF and Microwave Filters Anatech Electronics launched two new websites—anatechelectronics.com (for custom products) and AMCrf.com (Web store for online purchases)—that provide technical information for designers and make it easier to specify the company's RF and microwave filters. The anatechelectronics.com site describes Anatech's custom filter design fabrication capabilities. The AMCrf.com...
