cc2530如何调整发射和接收功率

大神们好,小弟问一下在带PA和不带PA的情况下如何调整2530的发射和接收功率啊,最近产品在距离上出了点问题,急求啊!

发射功率： 

/* Proprietary */
#if defined (HAL_PA_LNA)
19, /* phyTransmitPower for CC2591 */
#elif defined (HAL_PA_LNA_CC2590)
11, /* phyTransmitPower for CC2590 */
#else
0, /* phyTransmitPower without frontend */
#endif

也可以通过macRadioSetTxPower函数来修改发射功率。

接收：

/* minimum receiver sensitivity in dBm (see 6.5.3.3) */
#define MAC_SPEC_MIN_RECEIVER_SENSITIVITY -85

以及 

/* Threshold above receiver sensitivity for minimum energy detect in dBm (see 6.9.7) */
#define MAC_SPEC_ED_MIN_DBM_ABOVE_RECEIVER_SENSITIVITY 10
