AD9361

The AD9361 is a high performance, highly integrated radio frequency (RF) Agile Transceiver™ designed for use in 3G and 4G base station applications. It is developed and manufactured by Analog Devices company. Its programmability and wideband capability make it ideal for a broad range of transceiver applications. The device combines a RF front end with a flexible mixed-signal baseband section and integrated frequency synthesizers, simplifying design-in by providing a configurable digital interface to a processor. The AD9361 receiver LO operates from 70 MHz to 6.0 GHz and the transmitter…

AD9371

What is AD9371 ? The AD9371 is a highly integrated, wideband RF transceiver offering dual channel transmitters and receivers, integrated synthesizers, and digital signal processing functions. The IC delivers a versatile combination of high performance and low power consumption required by 3G/4G micro and macro BTS equipment in both FDD and TDD applications. The AD9371 operates from 300 MHz to 6000 MHz, covering most of the licensed and unlicensed cellular bands. The IC supports receiver bandwidths up to 100 MHz. It also supports observation receiver and transmit synthesis bandwidths up…

Altium Designer

Altium Designer is a PCB and electronic design automation software package for printed circuit boards. It is developed by Australian software company Altium Limited. Altium Designer’s suite encompasses four main functional areas: schematic capture, 3D PCB design, Field-programmable gate array (FPGA) development and release/data management. Noteworthy features referred to in the reviews include: Integration with several component distributors allows search for components and access to manufacturer’s data Interactive 3D editing of the board and MCAD export to STEP Cloud publishing of design and manufacturing data Simulation and debugging of the FPGA can be achieved using the VHDL language and checking that for a given a set of input signals the…

Antifuse

An antifuse is an electrical device that performs the opposite function to a fuse. Whereas a fuse starts with a low resistance and is designed to permanently break an electrically conductive path (typically when the current through the path exceeds a specified limit), an antifuse starts with a high resistance and is designed to permanently create an electrically conductive path (typically when the voltage across the antifuse exceeds a certain level). This technology has many applications.

ASIC

An application-specific integrated circuit (ASIC) is an integrated circuit composed of electrical components, such as transistors, capacitors, and resistors, fabricated on a wafer com-posed of silicon or other semicon-ductor material that is customized for a particular use. ASIC customized for a particular use, rather than intended for general-purpose use. For example, a chip designed to run in a digital voice recorder or a high-efficiency bitcoin miner is an ASIC. Application-specific standard products (ASSPs) are intermediate between ASICs and industry standard integrated circuits like the 7400 series or the 4000 series.…

chip

A small piece of semiconducting material (usually silicon) on which an integrated circuit is embedded. A typical chip can contain millions of electronic components (transistors). Computers consist of many chips placed on electronic boards called printed circuit boards. chip allows for more sophisticated functionality and faster arithmetic, which in turn leads to faster computation and less power consumption. There are different types of chips. For example, CPU chips (also called microprocessors) contain an entire processing unit, whereas memory chips contain blank memory. Chips come in a variety of packages. The three most common are: DIPs :Dual in-line…

EEPROM

EEPROM stands for Electrically Erasable Programmable Read-Only Memory and is a type of non-volatile memory used in computers, integrated in microcontrollers for smart cards and remote keyless systems, and other electronic devices to store relatively small amounts of data but allowing individual bytes to be erased and reprogrammed. EEPROMs are organized as arrays of floating-gate transistors. EEPROMs can be programmed and erased in-circuit, by applying special programming signals. Originally, EEPROMs were limited to single byte operations which made them slower, but modern EEPROMs allow multi-byte page operations. It also has…

EPROM

An EPROM (rarely EROM), or erasable programmable read-only memory, is a type of memory chip that retains its data when its power supply is switched off. Computer memory that can retrieve stored data after a power supply has been turned off and back on is called non-volatile. It is an array of floating-gate transistors individually programmed by an electronic device that supplies higher voltages than those normally used in digital circuits. Once programmed, an EPROM can be erased by exposing it to strong ultraviolet light source (such as from a…

Flash

Flash memory is an electronic (solid-state) non-volatile computer storage medium that can be electrically erased and reprogrammed. Toshiba developed flash memory from EEPROM (electrically erasable programmable read-only memory) in the early 1980s and introduced it to the market in 1984.[citation needed] The two main types of flash memory are named after the NAND and NOR logic gates. The individual flash memory cells exhibit internal characteristics similar to those of the corresponding gates. While EPROMs had to be completely erased before being rewritten, NAND-type flash memory may be written and read…

FPGA

Field Programmable Gate Arrays (FPGAs) are semiconductor devices that are based around a matrix of configurable logic blocks (CLBs) connected via programmable interconnects. FPGAs can be reprogrammed to desired application or functionality requirements after manufacturing. A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by a customer or a designer after manufacturing – hence the term “field-programmable”. The FPGA configuration is generally specified using a hardware description language (HDL), similar to that used for an application-specific integrated circuit (ASIC). Circuit diagrams were previously used to specify the configuration, but this…
