d) not exceed 27.0 dBW. 3.1.2.10.2.1 Inactive state transponder output power. When the transponder is in the inactive state the peak pulse power at 1 090 MHz plus or minus 3 MHz shall not exceed –50 dBm. The inactive state is defined to include the entire period between transmissions less 10-microsecond transition periods preceding the first pulse and following the last pulse of the transmission. Note.— Inactive state transponder power is constrained in this way to ensure that an aircraft, when located as near as 185 m (0.1 NM) to a Mode A/C or Mode S interrogator, does not cause interference to that installation. In certain applications of Mode S, airborne collision avoidance for example, where a 1 090 MHz transmitter and receiver are in the same aircraft, it may be necessary to further constrain the inactive state transponder power. 3.1.2.10.2.2 Spurious emission radiation Recommendation.— CW radiation should not exceed 70 dB below 1 watt. 3.1.2.10.3 SPECIAL CHARACTERISTICS 3.1.2.10.3.1 Mode S side-lobe suppression Note.— Side-lobe suppression for Mode S formats occurs when a P5 pulse overlays the location of the sync phase reversal of P6, causing the transponder to fail to recognize the interrogation (3.1.2.4.1.1.3). Given a Mode S interrogation that requires a reply, the transponder shall:
