When pins RT1 and RT2 are shorted to ground, the tem-
perature compensation circuit is disabled automatically.
Polarity of the temperature coefficient TC1 (or TC2), can
be selected by either shorting the RP1 pin (or RP2 pin)
to ground or leaving it open, while the coefficients’ values
can be controlled by external resistors RT1 and RT2 inde-
pendently, according to Figures 10 and 11. At a given RF
frequency, the polarities and optimal values of TC1 and TC2
can be chosen to ensure a stable output over the operating
temperature range. Table 2 lists the suggested RP1, RP2,
RT1 and RT2 values at various RF frequencies for the best
output performance over temperature.
