Abstract
Power measuring receiver (PMR) methods and apparatus for measuring power of signals are provided in which a high frequency measuring circuit (HFMC), a conversion measuring circuit (CMC), and an intermediate frequency measuring circuit (IFMC) work in conjunction with each other to measure a wide power range of signals. The HFMC may measure relatively high power signals at high frequency. The CMC may convert the high frequency signal into an intermediate frequency signal so that both the CMC and the IFMC can accurately measure low power signals. The CMC may also set the minimum noise bandwidth associated with gain stages in the IFMC. The intermediate frequency may provide the IFMC with the ability to perform low power measurements at a reduced DC power consumption.
