August 2007 - Rev 03-Aug-07 P1006-BD App Note [1] Biasing - This device is biased by applying Vd(1,2,3) = 8.0V with a total drain current I(total)=4.2 A. The gate bias can be applied in one of three ways by using either Vgg (Pin #2), Vgr (pin #18) or Vg (pin #3 or #17). 1) Vgg (pin #2) applies a scaled gate voltage to all FETs through a FET / resistor divider (Vto compensated) bias network. Applying -5V to Vgg (pin #2) will typically draw 4.2A with no further adjustment necessary. Wafer lot variation may result in some devices experiencing higher or lower drain currents than the typical 4.2A. 2) Vgr (pin #18) applies a scaled gate bias to all FETs through a resistive divider network. Applying -5V to Vgr (pin #18) will typically draw 4.2A, however, the gate bias will need to be actively adjusted to regulate the desired drain current. 3) Vg (pin #3 or pin #17) provides a direct gate bias input to all the MMIC stages. This method of biasing allows the user to control the total drain current, without the scaling factor. The typically gate bias for operation is -0.9V. Make sure to sequence the applied voltage to ensure that negative gate bias is available before applying the positive drain supply. App Note [2] Bias Arrangement - Each DC pad (Vd1,2,3 and Vg1,2,3 or Vgg) needs to have DC bypass capacitance (~100-200 pF) as close to the device as possible. Additional DC bypass capacitance (~0.01 uF) is also recommended.
