Dear all,
I use the ADPA9002 in a 4 ways TR module. For one way, the supply current is only about 328 mA instead of 385 mA indicated in the datasheet. In small signal, the ADPA has a gain of 12.7 dB (including a 1,2 dB lossy filter and 1,3 dB lossy bias tee, MBT-283+, Minicircuit). The input losses are OK.
The OIP1 measured is only about 25 dBm with IDD = 361 mA.
Is it normal to have such low consumption ? (VGG1 = GND and VDD = 11.36 V)
thanks a lot !
Laurence
