300-3000 MHz RF Detector

An RF detector with a dynamic range of 40 dB can now be obtained from Linear Technology (http://www.lineartech. com/pdf/5505i.pdf). The type LTC5505, housed in an SOT23 SMD package, can handle input frequencies between 300 MHz and 3 GHz for input signal levels between –32 dBm and +18 dBm (0 dBm = 1 mW into 50 ?). There are two versions having different input level ranges, as shown in the table.
