Research - Product Category. Wireless Infrastructure Digital Radio Products - Wideband Digital Transmit and Receive Solution - GC5330. The GC533x is a wideband transmit and receive signal processor that includes digital downconverter / upconverter (DDUC), transmit, receive, and capture buffer blocks.
The transmit path includes crest factor reduction (CFR), digital predistortion (DPD) and associated feedback path, complex equalization, and bulk upconversion. The receive path includes wideband and narrowband automatic gain control (AGC), bulk downconversion, complex equalization, and I/Q imbalance correction. The DDUC section consists of four identical DDUC blocks, each supporting up to 12 channels. Each channel has independent fractional resamplers and NCOs to enable flexible carrier configurations. Multi-mode/multi-standard operation can be supported by configuring the individual DDUC blocks to different filtering and oversampling scenarios.
A higher DPD bandwidth is possible with reduced DPD performance. SX1231H Low Power Integrated UHF Transceiver with On-Chip +20dBm PA. CMX991 RF Quadrature Transceiver IC for High Performance (100MHz to 1GHz RF) Focusing on narrowband communications, CML’s ICs are found in a wide range of PMR, wireless data, digital voice and marine radio applications, such as TETRA, DMR, dPMR, SCADA systems and AIS.
The CML portfolio provides components supporting both RF and baseband functionality, encompassing leading edge digital and legacy analogue systems. The following product groups are described in detail within dedicated pages on the site and can be accessed from the links shown on the left: Analogue TWR / Digital PMR (DPMR) - Two-Way Radio products providing the full baseband and individual communication requirements of analogue and digital military, PMR, trunked and leisure radio systems. Wireless Data - products addressing a wide range of communications and control applications, offering operation to custom, free-format and packet data systems.

Obsolete Products. Zynq-7000 SoC ZC702 Evaluation Kit. Zynq-7000 SoC / Analog Devices Software-Defined Radio Kit. Zedboard. Lime Microsystems. The LMS6002D is the world’s first field programmable RF (FP-RF) transceiver IC and remains the most flexible transceiver IC available in the market.
The transceiver IC can run on any standard and on any commonly used mobile communications frequency – both licensed and unlicensed - making it ideal for any wireless communications and broadband project. The LMS6002 is ideal for a wide range of applications, including M2M, SDR, comms equipment and consumer technology. For example, the proven technology has been used by private companies, governmental and military organisations to create a myriad of wireless broadband technologies - from whitespace radios to disaster relief networks to communications infrastructure devices and a list of all Lime customer case studies can be found here.
Technical specifications The LMS6002D can be digitally configured to operate on any mobile communications frequency bands (300MHz to 3.8GHz) and be used any 2G, 3G or 4G mobile communications standard. TI and Azcom develop DSP based cognitive radio solutions - RF&WirelessBlog. TI is now offering a portfolio of cognitive radio solutions, based on its TMS320C66x DSP.
Cognitive radio, a collective term referring to Super WiFi, WiFar, Wireless Regional Area Networks (WRAN), IEEE 802.11af, 802.22 and TV white spaces, is geared towards optimising the use of available spectrum and expanding global access to the Internet. TI’s KeyStone-based TMS320TCI6614 and TMS320TCI6612 SoCs, which encompass a mix of radio accelerators, network and security coprocessors as well as fixed-and floating-point DSPs and an ARM RISC processor, provide a foundation for layers 1, 2 and 3 and transport processing for cognitive radio.
The company’s new TMS320C665x processors are also suited to cognitive radio and consist of three fully pin compatible low-cost, power optimized solutions for developers migrating from single core to multicore. Azcom Technology is also designing LTE and IEEE 802.22 standard boards based on TI’s wireless infrastructure SoCs.
