Catalog covers pulsed laser diodes and avalanche photodiodes
LASER COMPONENTS presents a new catalog of pulsed laser diodes (PLD) and avalanche photodiodes (APD). The latest innovative products include the world’s fastest PLD and APD arrays with several sensor elements embedded into one electronic component. All the products featured in the catalog have been developed and produced by LASER COMPONENTS in Canada and the […]
Why use a nonlinear amp?
Users normally place a great deal of value in the high linearity of an amplifier and its corresponding low distortion. Audio amplifiers, for example, are quoted with many linearity specifications, such as total harmonic distortion (THD) or 1%, 0.1% or even less. Even the outputs of amplifiers with internal topologies which are inherently nonlinear, such […]
What is a multiplying DAC?
Multiplying digital-to-analog converters (MDACs) produce a (current) output signal that’s a product of the given reference voltage and the code (i.e., a string of 0s and 1s) flowing through it. All data converters require a voltage reference (VREF) and a typical, standard DAC needs a very stable fixed reference voltage in order to operate properly. […]
16-channel, 12/16-bit DACs target telecom optical-module control
Analog Devices, Inc. announced today a pair of highly integrated 16-channel digital-to-analog (D/A) converters that significantly reduce the system footprint for wired telecommunications systems, yet without any performance compromise. The 12-bit AD5767 and 16-bit AD5766 are fully integrated devices with all the required bias ranges for coherent optical systems of medium- to long-haul, fiber-based telecommunication […]
Optocoupler selection and usage for isolating a PWM
An optocoupler (or optoisolator) is a device that galvanically separates circuits and is not only great at isolation but allows you to interface to circuits with different ground planes or that operate at different voltage levels. Optocouplers are “fail safe” in that if subjected to voltages higher than the maximum rating, they are known to […]
RF switch protects receivers for MIMO, emerging radio architectures
Peregrine Semiconductor Corp. introduces the UltraCMOS PE42823, a high-power receiver protection RF switch. Ideal for wireless infrastructure applications, this reflective switch is optimized for emerging radio architectures such as massive multiple input, multiple output (MIMO). The PE42823 delivers excellent single-event peak power handling, low power consumption, and high linearity. Offered in a compact form factor, […]
MEMS accelerometer provides non-linearity below 0.05%
TDK Corporation announces the Tronics AXO215 high-performance MEMS accelerometer that sets the benchmark in terms of miniaturization, reliability and inertial sensing performance in harsh environments. Developed by Tronics Microsystems, a TDK Group Company that designs and manufactures innovative nano and microsystems, the new closed-loop accelerometer complements the lineup of TRONICS GYPRO sensors. The new accelerometer […]
What does an analog driver/buffer do?
The term “buffer” has many definitions in electronics hardware and software. It can be a reserved software area where data is temporarily stored until it is processes; a set of internal IC registers where data is queued before being transmitted or after it has been received; or it can be a circuit function interposed to […]
Wideband plastic MMICs include power amps and switches
Microsemi Corporation announced a new family of wideband plastic packaged and chip monolithic microwave integrated circuit (MMIC) devices. The new products adds to a growing portfolio of high-performance wideband MMICs and include four plastic packaged low noise amplifiers (LNAs), MMA040PP5, MMA041PP5, MMA043PP4 and MMA044PP3; a wideband power amplifier (PA) chip, MMA053AA; and two plastic packaged switches, MMS006PP3 and MMS008PP3. The new MMIC products will […]
