Re: Will this hurt my radio? said by Jerm:Anyone know at what point damage might be done to a radio? -40 and higher? What might be safe? The long term damage potential can be clarified by the RF circuit designer at Tranzeo. The typical antenna TX/RX switch is OK with 0dBm level but many 802.11 receiver circuits saturate with much lower RSSI.
This is a result of biasing analog-to-digital converter for very low level signals like -90dBm which occur in indoor wireless LANs. Even with 12-bit ADC circuit, the saturation point will be in the -30dBm range. With 8-bit ADC it will be in the -50dBm range. |
