Crystek's CVCO33BE-1662-1708 VCO (Voltage Controlled Oscillator) operates from 1662 to 1708 MHz with a control voltage range of 0.5 ~ 4.5 V. This VCO features a typical phase noise of -106 dBc/Hz @ 10KHz offset and has excellent linearity. Output power is typically +2 dBm.
Mobile Experts released a report that predicts a new future for base station semiconductors. In particular, the number of base station transceivers will grow to more than 17 million per year by 2017. Increasing bandwidth requirements, MIMO, and carrier aggregation will drive growth in key semiconductor components. The new report, "Semiconductors for Macro Transceivers and RRH," gives a detailed analysis of these trends.
As the mobile network struggles to cope with the growing level of traffic and pressures on CAPEX, the RF electronics of a typical base station design are subject to great innovation namely in the form of tower mounted amplifiers, remote radio heads, and active antennas.
Tower top RF electronics, consisting of active antennas, remote radio heads, and tower mounted amplifiers, are important parts of modern macro base station hardware.
Freescale Semiconductor announced new two-stage, low-noise amplifiers (LNAs) that address two gain stages in one device and deliver coverage across multiple bands to simplify wireless base station designs.
Wireless infrastructure equipment revenues continued their downward trend in the second quarter of 2012 reaching only $11.2 billion – a 4.7 percent decrease from the first quarter of 2012 and a 14 percent decrease from the same quarter one year ago. “Total revenues for wireless network equipment reported by the vendors was the lowest amount that we have seen since 3Q 2003; reaching a 35 quarter low,” says Nick Marshall, principal analyst, networks.
The demands of cost reduction and greater efficiency in cellular base station design are leading to a rapidly growing market for remote radio heads. According to a new study from ABI Research, this market is on track to exceed a value of $1 billion in 2017. Cellular base stations are now undergoing a design revolution. A base station was traditionally a rack of equipment inside a shelter. That design is now becoming anachronistic because it is expensive, and because the required coaxial cable running up the tower to the antennas often results in significant losses of power.
ABI Research expects sales of base station processors to grow at 17 percent annually and reach $1.1 billion in 2017 driven by the growth in compact format femto-, pico-, and microcell small cell basestations, which will account for the majority of the processor market in 2017. With macrocells declining at 13 percent per year over the next 5 years, and microcells growing at a modest 7 percent the large growth in picocells and outdoor femtocells will consume the majority of next generation base station processors.
IQD’s new IQOV-70 series OCXO, which is launching at Embedded World 2013, is designed for use in next generation multimode base station platforms. Operating at a frequency of 10 MHz, the new model achieves a frequency stability of ±3 ppb (parts per billion) over the operating temperature range of -10° to +70°C.
Response Microwave Inc., a global specialist in providing RF/Microwave customer solutions, is pleased to announce the availability of its new coupler series for use in 802.11n and MIMO point-to-multipoint telecom base station applications.
