The CMX972 Quadrature Modulator/Demodulator is the latest RF building block from CML Microcircuits, following on from the popular CMX970, CMX971 and CMX973 devices.

The market for chipsets containing LTE baseband processors has ramped up quickly, and is fraught with competition. 15 companies offer over 35 chipsets with LTE, from singlemode LTE chipsets to multimode chipsets integrated with application processors and wireless connectivity. ABI Research’s latest Competitive Assessment ranked Qualcomm first in LTE baseband product features and other attributes, followed by ST-Ericsson and Sequans.

Mobile device design is increasingly reliant on integrated platforms, which are chipsets based on combinations of application processor, baseband processor, and wireless connectivity technologies. In 2012, 19 percent of handsets shipped were based on an integrated platform; set to more than double to 46 percent in 2018.

Maxim Integrated Products Inc. announced the MAX2173 RF to Bits tuner for digital audio broadcast (DAB) applications in automobiles and other mobile DAB/FM products. The industry’s first RF to Bits DAB/FM tuner integrates a radio tuner, analog-to-digital converter (ADC), and digital filtering, and uses a digital I2S output to interface directly to digital signal processors (DSPs).

RF Micro Devices Inc., a global leader in the design and manufacture of high-performance radio frequency solutions, announced it has been selected by a leading smartphone manufacturer to supply multiple 3G/4G LTE components into a recently announced fourth-generation flagship smartphone platform.

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.

Elcom’s UFS‑18 low phase noise, coherent frequency synthesizer can now provide wideband coherent chirp waveforms at frequencies up to 18 GHz. Modulation bandwidth of ±100 MHz is possible.
