ADPA7005 Constant Current Consumption without RF input

Category: Hardware
Product Number: ADPA7005
Software Version: N/A

Hi there,

Or goal is the understand the total current consumption including IDD and IDQ on the ADPA7005 at ON stage with NO RF input. 

So we want to configure IDQ to 1400mA pre datasheet, does this mean IDQ will draw at a constant of 1400mA even without RF signal at the input? 

In addition, from Figure34 of the datasheet IDD also look constant with Pin below 5dBm. Does this mean the current consumption is other IDD = 1400mA addition to IDQ=1400ma form above?

Thank you,

  • Hi NamPh,

                      IDQ is the quiescent current, (no RF applied). IDD is the current drawn by the amplifier during use. at low input power levels, the IDD will remain close to the IDQ value and as you drive the amplifier harder the current will increase as shown in Figure 34 above.
