摘要： Part of a first signal path for amplifying a signal includes circuits for detecting a signal, and a second signal path connected to an input portion of the first signal path includes circuits for detecting the signal. A signal strength detector circuit adds outputs from the respective detector circuits in the first and second signal paths. The first signal path has a function of expanding the dynamic range in a smaller signal region as compared with the second signal path, while the second signal path has a function of expanding the dynamic range in a larger signal region as compared with the first signal path. When a radio transmitted output is variably controlled in a radio transmitter section based on a field strength detection output for a received signal, the transmitted output is optimized, resulting in minimizing consumed power and unnecessary radiation of radio waves.

摘要： An electronic component for high frequency power amplification realizes an improvement in switching spectrum characteristics. The gain of an amplifying NMOS transistor is controlled by a bias voltage on which a bias control voltage is reflected. Further, a threshold voltage compensator compensates for a variation in threshold voltage with variations in the manufacture of the amplifying NMOS transistor. The threshold voltage compensator includes an NMOS transistor formed in the same process specification as the amplifying NMOS transistor and converts a variation in current flowing through the NMOS transistor depending on the variation in the threshold voltage of the amplifying NMOS transistor to its corresponding voltage by a resistor to compensate for the bias voltage. It is thus possible to reduce variations in so-called precharge level brought to fixed output power in a region (0 dBm or less, for example) low in output power.
