10-12-2013 | A fundamental property for the first microwave amplifier in a radio receiver is its noise figure. This is normally given in decibel (dB). A...

1-05-2011 | Decent potentiometers for setting the volume in amplifiers are still quite expensive. However, there is a cheaper alternative, and it’s bett...

1-07-2000 | The signal from a microphone is two weak for a standard line input. This low-noise DC-coupled microphone amplifier provides a solution for a...

1-12-1998 | This preamplifier was designed for low-impedance signal sources like MC (moving-coil) pick-up cartridges used in highend record players...

1-12-1998 | The MGA-86563 from HewlettPackard is a three-stage, GaAs, MMIC (monolithic microwave integrated circuit) that offers low noise figure an...

1-06-1996 | Amateur television (ATV) is among the most popular, technically advanced and exciting sub-activities available to the licenced radio am...

1-07-1993 | With the arrival of matched transistors in a single package it seems that the quest for the zero-noise microphone preamplifier has receive...

1-12-1992 | One way of desigining a low-noise amplifier is the shunting of several input stages. This reduces the overall noise, Un=U(i)n-1/2, where...

1-12-1992 | Opamp TypeSSM2017 from PMl is eminently suitable for designing a very-Iow-noise microphone preamplifier.

1-10-1992 | This design goes to show that low noise and substantial amplification can go hand in hand in a single amplifier with excellent wideband ch...
