Application Circuit
TGA2567-SM
2-20 GHz LNA Amplifier
Notes: To prevent damage to the device due to overshoot or oscillation issues, we recommend that current limits for all power
supplies are set properly for each power supply before applying the voltage. The following are recommended current limits for
each power supply:
Set 10 mA current limit to VG1 and VG2
Set 140 mA current limit to VD
Bias-up Procedure
1. Apply -1.5 V to VG1.
2. Apply +5 V to VD.
3. Apply +1.3 V to VG2.
4. Adjust VG1 until IDQ = 100 mA (VG1 ~ -0.7 V Typ.).
5. Turn On RF supply.
6. Adjust VG2 to obtain desired gain
Bias-down Procedure
1. Reduce VG2 to +1.3 V.
2. Turn off RF supply.
3. Reduce VG1 to -1.5 V. Ensure IDQ ~ 0 mA
4. Set VG2 to 0 V.
5. Set VD to 0 V.
6. Set VG1 to 0 V.
