The coupler uses coupled inductors with a compensation circuit including a resistor and a capacitor, or just a capacitor. Wideband operation is suitable for many portable applications such as power detection and control for GSM, DCS-PCS, CDMA/WCDMA, Bluetooth, and WLAN systems.

摘要： An RF power amplifier circuit and input power limiter circuits are disclosed. A power detector generates a voltage output proportional to a power level of an input signal. There is a directional coupler with a first port connected to a transmit signal input, a second port connected to the input matching network, and a third port connected to the power detector. A first power amplifier stage with an input is connected to the input matching network and an output is connected to the transmit signal output. A control circuit connected to the power detector generates a gain reduction signal based upon a comparison of the voltage output from the power detector to predefined voltage levels corresponding to specific power levels of the input signal. Overall gain of the RF power amplifier circuit is reduced based upon the gain reduction signal that adjusts the configurations of the circuit components.

摘要： A field-confined wideband antenna assembly is disclosed. The antenna assembly includes a radiating element with a planar body that defines a first confining slot. The dimensions of the first confining slot correspond to a first set of resonance frequencies of the radiating element. A feeding line extends from the radiating element in an angularly offset relationship to the planar body. A first grounding line extends from the radiating element in an angularly offset relationship to the first body. A dielectric assembly supports the planar body of the radiating element. There is a first high frequency current loop that is formed from the feeding line to the radiating element about the first confining slot and to the first grounding line. With this, the first high frequency current loop confines current and electric fields on the radiating element.
