50-MHz decibel-milliwatt (dBm) meter
Two high-level integration circuits, the AD606 from Analog Devices and the MAX13RCPL from Maxim, enable an accurate, widehand voltage and power meter to be built using a minimum of components. The instrument described here offers a 3.5-digit LCD readout and a handwidth of 50 MHz. The input level range is quite large at -80 to +10 dBm at a resolution of 0.1 dB. The input impedance is 50 Ω.
