Using, for instance, Fig. 4 from Recommendation ITU-R SF.766, one finds that the C/N is degraded by about 0.8 dB where the C/I is 8 dB more than the C/N, i.e. 33 dB. The unfaded interference power is Ir Cr – 33 –10 ...

... The STPM01 normally uses a resistor divider as voltage input channel (see Figure 9). The 783kΩ resistor is separated into three 261kΩ, in-series resistors (see Figure 1 on page 5), which ensure that a high voltage transient will not bypass the resistor. These three resistors also reduce the potentia ...

Valve RF amplifier
A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical radio frequency signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of transmitters, transmitter output stages switching to transistors somewhat later. Specially constructed valves are still in use for very high power transmitters, although rarely in new designs.
