摘要： An RF circuit (131–138) satisfies Pnoise+NF+G≦Plim+sW (0≦s≦4) at an edge of a guard band with respect to a required transmission level PAll, an upper tolerance level of out-of-band noise Plim, a guard bandwidth W, and a noise level Pnoise, where NF is a noise figure and G is a gain. An IF circuit (121–123) satisfies PAll≦Pin+G, where PIF is an output level of a BPF (123). Out-of-band noise levels are reduced to Pnoise by the steep BPF (123). The RF circuit (131–138) is structured so that noise from a local oscillator circuit (134) does not surpass noise from the IF circuit (121–123). Reductions in power consumption are thus realized in addition to guard bandwidth reductions, because of being able to eliminate out-of-band noise from an amplifier (138) using a low-loss filter (140) having an attenuation slope s.
摘要翻译： 射频电路（131-138）在保护频带的边缘相对于所需传输电平PAll满足Pnoise + NF + G <= Plim + sW（0≤s≤4），上限公差电平 带宽噪声Plim，保护带宽W和噪声电平Pnoise，其中NF是噪声系数，G是增益。 IF电路（121-123）满足PAll <= Pin + G，其中PIF是BPF（123）的输出电平。 陡峭的BPF（123）将带外噪声水平降低到Pnoise。 RF电路（131-138）被构造成使得来自本地振荡器电路（134）的噪声不超过来自IF电路（121-123）的噪声。 由于能够使用具有衰减斜率s的低损耗滤波器（140）能够消除来自放大器（138）的带外噪声，因此除了保护带宽降低之外，还实现功耗的降低。

摘要： A radio apparatus includes an antenna (104), and a transmission circuit (102) and a receiving circuit (105) sharing the antenna. The apparatus connects an output of the transmission circuit to an input of the receiving circuit in calibration for calculating the quantity of phase rotation and/or the quantity of amplitude fluctuation of a signal passing through the transmission and receiving circuits. Then, it connects a reference signal to the input of the receiving circuit for calculating the quantity of phase rotation and/or the quantity of amplitude fluctuation of a signal passing through the receiving circuit. Based on the subtraction of the information, the quantity of phase rotation and/or the quantity of amplitude fluctuation of a signal passing through the transmission circuit is calculated. It calculates a correction value for correcting difference in quantity of phase rotation and/or quantity of amplitude fluctuation between the transmission and receiving circuits on the basis of the information. Thus, the difference in quantity of phase rotation and/or quantity of amplitude fluctuation between the transmission circuit and the receiving circuit can be corrected.
