6.8-7.9 GHz GaAs MMIC
Voltage Controlled Oscillator
May 2005 - Rev 05-May-05
7OSC0463
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.
These numbers were calculated based on accelerated life test information and thermal model analysis received from the fabricating foundry.
