by Chris Francis When dealing with high speed, low noise, non 50 ohm systems such as transimpedance amplifiers, a GaAsFET or HEMT can be a viable choice. On the face of it, devices such as the ATF35143 from Avago (previously known as Agilent) have suitable characteristics – low noise, low bias current and high bandwidth. […]

Linear Technology LT8614 “SilentSwitcher”
The Linear Technology LT8614 “SilentSwitcher” claims to reduce EMI/EMC emissions to well below the CISPR 25 Class 5 limit. It also seems a well specified step-down switching regulator with 2.5µA quiescent current, up to 42V input and 4A output current. It also has a high efficiency of 96% at 1MHz (it is a synchronous regulator). […]
