GaN MMIC amplifier covers 300 MHz to 6 GHz
Analog Devices, Inc. introduced a wideband gallium nitride (GaN) power amplifier that offers best-in-class performance within a compact design. Covering the 300 MHz to 6 GHz spectrum, the highly integrated HMC8205 provides significant benefits for system designers of applications such as wireless infrastructure, radar, public mobile radio, and general-purpose amplification test equipment that require pulse […]
Top analog threads on EDAboard.com – May
(editor’s note: Intrigued by the problem? Have a question or another solution? Then click the “Read more” link and follow the conversation on EDAboard.com or log in to EDAboard and participate in the analog forum threads.) Flyback source and magnetic air gap – I was studying dc-dc converters because I want to do a flyback voltage […]
Piezoelectric sounder puts out 100 dB to alert vehicle drivers
Murata Americas has introduced the PKMCS1818E20A0-R surface mount piezoelectric sounder for automotive applications that enables reflow mounting as an effective countermeasure against irregular mounting and abnormal sound. The product has a sound pressure level of 100 dB at 100mm and measures a diminutive 18 x 18 x 8 mm. Its wide operational temperature range means that it can operate in automobile cabin temperatures […]
Are your op amps pumped?
I was recently thinking about the issues surrounding rail to rail input opamps and the problems of making them low distortion – a problem I have had to overcome when designing integrated circuits for instrumentation applications. Some rail to rail opamps use two input stages – one using NMOS input transistors, the other using PMOS […]
Free-running reference oscillators span 10 MHz to 100 MHz with low phase noise
Pasternack has released six new free-running reference oscillators that generate a highly stable and accurate output frequency response with low phase noise and spurious performance levels, making them ideal in phase locked loops, function generators, frequency synthesizers and receivers for communication, radar, navigation, surveillance and test and measurement applications. These free-running, fixed-tuned oscillators use a high-stability […]
Making sense of thermocouples and interfaces, part 2
Part 1 of this FAQ looked at the basics of thermocouples, where and why they are used, and some basic implementation issues; this part explores interface issues, cold junction compensation, and linearization. What are the requirements for thermocouple interface electronics? The thermocouple voltage is relatively small, so long leads between the thermocouple and the electronic front-end […]
Single-chip millimeter wave sensors deliver range accuracy down to >50 micrometers
Texas Instruments new mmWave single-chip complementary metal-oxide semiconductor (CMOS) portfolio includes five solutions across two families of 76- to 81-GHz sensors with a complete end-to-end development platform. Available for sampling today, the AWR1x and IWR1x sensor portfolio delivers up to three times more accurate sensing than current mmWave solutions on the market. The combination of sophisticated analog […]
Super-accurate gyro modules target UAVs, precision ag and construction apps
MEMSIC Inc. announced the addition of the VG380 to its portfolio of inertial modules. These new vertical gyros provide highly accurate pitch and roll (with respect to gravity), in both static and dynamic conditions, at a very attractive size and price points. The static and dynamic accuracy is specified at +/-0.2 and +/-1.0 degrees (respectively) […]
Making sense of thermocouples and interfaces, part 1
Temperature is the most frequently measured real-world variable, and despite its age, thermocouples are still among the most-used temperature sensors. They are used in test and measurement equipment, instrumentation, and even in standard home ovens due to their low cost, reliability, simplicity, and ability to measure into hundreds of degrees. What is a thermocouple and […]
