Overview

The WEA520SFMCW22G is an ultra-fast ultra-linear FMCW frequency synthesizer capable of generating 1400 MHz Chirps at 20 GHz frequency. It uses a reference input ranging from 20 MHz to 200 MHz, with the use of an external Crystal or clock (CMOS or LVDS). The WEA520SFMCW22G generates an RF signal spanning from 3.5 GHz up to 20.25 GHz with the four integrated VCOs and the use of an RF frequency doubler and divider. The synthesizer utilizes the WEASIC proprietary WeCHIRPTM, wePACTM, weCALTM technologies to provide very fast ramp retracing and settling times while maintaining industry leading phase noise during chirping. The modulator has a phase synchronization capability for coherent operation with other modulators. It also provides synchronized trigger event signals for the RADAR Transmitter and Receiver chips. By the use of internal high PSRR LDOs, the WEA520SFMCW22G can withstand noisy power supply environment. It is powered by a single 1.8 V supply

Three Major Inflection Points for Sourcing Bluetooth Intellectual Property

Synopsys is now shipping support for Bluetooth® 5.4, the latest specification from the Bluetooth SIG (Special Interest Group). The enhancements in Bluetooth 5.4 will open additional markets and use cases. This is one of the many inflection points in the Bluetooth Low Energy market that will be discussed in this paper.

Part 2: Opening the 5G Radio Interface

Carriers are now deploying 5G across the globe driven by the need to keep up with relentless mobile data growth. 5G New Radio (NR) operates at higher frequencies to increase bandwidth, but at the expense of range. There will therefore be a need for a much larger number of 5G RUs to provide the same coverage. The availability of cost-effective, reliable and open 5G radio units is therefore critical.

An Integrated, Tunable RF Filter: an Enabler for Reconfigurable Front-Ends

This paper presents the design and performance of a key RF circuit necessary for the realization of a reconfigurable, integrated RF front-end: a tunable frequency, selectable bandwidth, on-chip, “SAW replacement” filter. The on-die tunable filter presented here has a tunable center frequency up to 1 GHz, a selectable bandwidth up to 40 MHz, and an adjacent channel rejection down to 60 dB.

Design considerations for integrated CMOS receivers

To meet the demands for the multi-band, multi-mode wireless standards in the current market, a highly integrated wireless receiver (RX) is desired. CMOS technology has become the technology of choice for the integrated receiver design.

Silicon IP for Programmable Baseband Processing

An efficient IP reuse strategy relies on IP blocks with wide applicability. That makes generic blocks, such as programmable processors preferable. However, in many applications such as handheld wireless terminals, additional silicon area and power consumption compared to fixed function solutions can not be accepted.
