RF OUT

Vg = -0.55V

Typical

Vg and Vd can be biased from either side, and the non-biased side can be left open.

(Vg are either pins 7 and 8 or pins 23 and 24, Vd are either pins 10 and 11 or pins 20 and 21)

Bias-up Procedure

Vg set to -1.5 V

Vd set to +6 V

Adjust Vg more positive until quiescent Id is 650mA.

This will be ~ Vg = -0.55 V

Apply RF signal to RF Input

Bias-down Procedure

Turn off RF supply

Reduce Vg to -1.5V. Ensure Id ~ 0 mA

Turn Vd to 0 V

Turn Vg to 0 V

The TGA2527-SM will be marked with the “2527” designator and a lot code marked below the part designator. The “YY”

represents the last two digits of the year the part was manufactured, the “WW” is the work week, and the “XXXX” is an auto-

generated number.
