radio workshop. Unfortunately, accurate, wideband models are fairly
expensive, and home-constructed ones are generally not sufficiently
sensitive and/or are very temperature-dependent. These drawbacks are
overcome by a device from Analog Devices which has recently become
available: a low-cost DC–500 MHz, 92 dB logarithmic amplifier that
enables an accurate, not too expensive RF decibel meter to be constructed.
A few small modifications make the meter also suitable for lowfrequency
measurements.
