It can be considered as sufficient to simulate the void reactivity feedback applying 6-node model, as shown while analyzing the neutron multiplication factor. Nevertheless, denser 6* nodes' model shows better congruence with reference case (deviation 2.4 pcm only), and it was chosen for performing the detailed sensitivity and uncertainty analysis.
(d) Estimate assumed that the prophylaxis program was initiated on postattack day 6 for anthrax and tularemia and postattack day 113 for brucellosis, that the prophylaxis program had the lower effectiveness level, and that the multiplication factor for unnecessary prophylaxis given to unexposed persons was 5.
The oscillator's phase noise within the loop bandwidth is a function of the noise of the external reference signal degraded by 20logN + 3 dB, where N is the multiplication factor applied to the reference to produce the output frequency.
The multiplication factor for this implementation is x5 and the subharmonic input signal frequency is 3.6 GHz.
Bipolar transistors can be used at frequencies as high as X-band, but the tradeoffs between minimum noise figure for the device and the degradation caused by frequency multiplication in choosing an optimum arrangement between starting frequency and the multiplication factor must be examined.
Therefore, the reference frequency must be as high as possible to keep the frequency multiplication factor in the PLL as small as possible.
The scalar analyzer displays the correct operating frequency by annotating the sweep display according to the multiplication factor. With the guided calibration prompts, quick and accurate measurement set-up is easily accomplished.
The functional specifications for the design are a multiplication factor of two; an input frequency of 925 MHz; an input power of 10 dBm; an output power of greater than 7 dBm; and a supply voltage of 3 V.
