While an amplifier provides gain, boosts the signal, an attenuator provides loss, reduces the signal. Attenuators are always a compromise and should only be used if absolutely necessary.

A design for an instrumentation amplifier with digitally programmable gain and common-mode rejection (CMR) trim is presented. A standard multiplying D/A converter (DAC) is used as the differential ...

This letter presents a distributed amplifier (DA) monolithic microwave integrated circuit (MMIC) achieving a bandwidth (BW) of 4–420 GHz with a small-signal gain of 11 ± 2 dB. This sets a new BW ...
