*6 Measurements are made using the radiant power measurement system on the hologram unit. The definition is presented in Fig. 2.
*7 Unless otherwise indicated, the values shown are per individual element.
*8 The subscript (mon) denotes the element (monitor PD).
*9 Ct(RF1) denotes the capacitance measured at pin No. 4 or 10 in the electrode connection diagram. Ct(RF2) denotes the capacitance
measured at pin No. 5 or 9 in the electrode connection diagram.
