De-Rating Chart

To maintain the FCC Spurious Emissions limit of -13 dBm maximum, for multiple
carriers it is necessary to de-rate their power level. For FM carriers, they need to be
de-rated as shown...

Number of Carriers

Power per Carrier

1 +37

dBm

2 +26

dBm

3 +24

dBm

4 +22

dBm

5 +20

dBm

6 +19

dBm

7 +18

9 +16

dBm

10 +15

15 +13

dBm

20 +11

dBm

25 +10

dBm

30 +9

dBm

For complex CDMA, TDMA, GSM, etc. carriers, typically de-rate by a further 3 to 5
dB. Consult Kaval for more information.
