App Note [1] Biasing - As shown in the bonding diagram, this device is operated by separately biasing Vee1, Vee2, Vee3 and Vtune with

Vee1 = Vee2 = Vee3 = -5.0 V and Vtune = 0.0 to 6.0 V, Iee1 = Iee2 = Iee3 = ~ 6.5 mA.

App Note [2] Bias Arrangement - Each DC pad (Vee1, 2, 3 and Vtune) needs to have DC bypass capacitance. (~100 - 200 pF, 100pF max on

Vtune) as close to the device as possible. The Vee3 pads have been tied together on chip and can be biased from either location.
