Si Push Pull, 40 – 870MHz, 21.5dB min. Gain @ 870MHz, 235mA max. @ 24VDC

Notes:

1) The slope is defined as the difference between the ´ideal gain´ at the start frequency and the ´ideal gain´ at the

stop frequency.

2) The gain flatness is the deviation of any amplitude value from the ideal gain curve calculated by the following

mathematical model: Gain = G + C*SQRT(f_x/f₁).

G = constant gain (frequency independent); C = cable constant; f_x= desired frequency; f₁= start frequency. The

cable constant C must be optimized during the flatness determination so that the curve best fits the measured

gain figures. The start value for C is calculated using the formula C_start= (G_n–G₁)/(SQRT(f_n/f₁)-1), where G_n= the

measured gain at the stop frequency, G₁= the measured gain at the start frequency and f_n= stop frequency.

The value of G is chosen so that the max. positive deviation of the measured gain from the ´ideal gain´ curve is

the same as the max. negative deviation. The value of C is adapted by ± 0.001 until the ´ideal gain´ curve best

fits the measured curve. The flatness of the module gain is the maximum deviation in measured gain from the

optimized gain formula.
