Power Supply Adjustment

The RFPD3580 can be operated at a power supply voltage V+ between 24V and 34V to provide maximum required linearity

performance at minimum power consumption. Maximum output capability can be adjusted between 73.8dBmV composite power

(= 58dBmV actual level at fmax equivalent to 64dBmV virtual level) at V+ = 24V and 76.8dBmV composite power (= 61dBmV

actual level at fmax equivalent to 67dBmV virtual level) at V+ = 34V under a pure digital loading (190 channels QAM256) with

22dB tilt.

Test Condition: TMB = 35°C; ZS = ZL = 75Ω, 22dB tilt, 190 digital channels (QAM256 ITU-T J.83 Annex B)
