CHA7012
(1) Parameter tunable by Vctrl when control biasing circuit used.
(2) This value corresponds to the 4 ports in parallel (Pin 4, 8, 14, 18)
(3) 0.5V variation on Vc leads to around 0.4dB variation of the output power (impact on

Operation of this device above anyone of these parameters may cause permanent
damage.
For higher compression the level limit can be increased by decreasing the voltage
Vc using the rate 0.5 V / dBc
