Software-Defined Radio Demonstrators: An Example and Future Trends

Table 1

RF specifications for various standards.

	GSM	UMTS	802.11 b
Noise figure (dB)	9	9.6^(2)	9^(3)
IIP2 (dBm)^(1)	43	8.0	10
IIP3 (dBm)	−18	−21.0	−18

⁽¹⁾IIP2 is required for zero-IF or low-IF architectures
⁽²⁾Assuming a processing gain of 25 dB
⁽³⁾Assuming a processing gain of 10.4 dB
