Figure 2-7.

Narrow-band 3-dB Blocking Characteristic at 315 MHz

Figure 2-8.

Wide-band 3-dB Blocking Characteristic at 315 MHz

Table 2-8

shows the blocking performance measured relative to –102 dBm for some frequen-

cies. Note that sometimes the blocking is measured relative to the sensitivity level 104 dBm
(denoted dBS), instead of the carrier –102 dBm (denoted dBC)
