dBm – a relative power level referencing 1 milliwatt. W – a linear power level referencing Watts. The relation between dBm and Watts can be calculated through the following formulas, dBm = 10 x log[Power in Watts / 0.001W] W = 0.001 x 10[Power in dBm / 10 dBm…

That means that an input of -5 dBm will give 0.5 watts out from the RF2125P. That, in turn, will drive the cascaded final amplifier stages to a full 80 watts, making a very nice high power package that can be driven by less than 1 milliwatt from a low-power transverter. The figure below shows the proposed line-up.

38 - 20 = 18 dBm. Converting this level to a reference bandwidth of 1 MHz results in an unwanted emission level: 18 + 10 Log (1x106/100x103) = 28 dBm . The receiver system noise level is computed using the following equation: N = -114 + 10 Log (BW) + NF (B-1) where: N = the receiver system noise level (dBm);

In its petition, Mark IV Industries argued that the 750 mW (28.8 dBm) maximum output power was overly restrictive and should be replaced with an antenna input power of up to 4 watts (36 dBm). Mark IV Industries also states that maximum output power limit does not account for cable loss in cases where a transmitter and the antenna are separated ...

(1) The output power shall not exceed -3 dBm watts for each frequency authorized. (2) The antenna used in transmitting the audible warnings must be omnidirectional with a maximum gain equal to or lower than a half-wave centerfed dipole above 30 degrees elevation, and a maximum gain of +5 dBi from horizontal up to 30 degrees elevation.
