RMS power detector offers a 67-dB measurement range

Suited for applications, such as communications infrastructure, power amplifier linearization, point-to-point and point and point-to-multipoint, cable, military, satellite, instrumentation equipment and ISM band transmitters, the ADL5906 TruPwr RMS detector features an operation up to 10 GHz, a 67-dB measurement range, and eliminates the need for external input tuning devices, such as a balun. This part features a temperature stability of less than ±1 dB from -40° to 85°C, an operating temperature from -55° to 125°C, and a power down capability to 250 µA.

Requiring only a single supply of 5 V and a few capacitors, the part is easy-to-use and capable of being driven with a single-ended or differential input drive. The detector is priced for 1k quantities at $5.59 and it is housed in a 4 x 4-mm, 16-pin LFCSP package.
