Analog Devices Inc. (Norwood, MA) unveiled what is claimed to be the industry's first RF IC that measures modulated-waveform power found in next-generation 3G infrastructure equipment, the AD8362, with a linear input and dB output that measures up to 2.7GHz over a 60dB range. The device has a measurement range from -45dBm to +15dBm within a 50 Ohm system and provides a 50mv/dB output-voltage scaling.
Operating on a single 5V supply and consuming just 19mA of quiescent current, the IC operates over a temperature range from -45 to +85 degrees C. Other integrated functions include error-correction and a precision bias circuit.
Available in a 16-lead TSSOP, the price is $6.25 for each 1,000 pieces.
