7 HPA MODULE plan to use the advance substrate TACLAM+ to deliver a module version of the PA. 7 / 13 APPLICATION SCHEMATIC To prevent unstability of the customer design it is hightly recommended to place a 47pF RF decoupling chip capacitor at each DC terminal with the shortest possible bonding wires. Additionnaly, a 10nF capacitor can be added on a drain connection. In the gate circuitry, a 500 Ω resistor have been added in serie with each gate introducing some low pass filtering in case of fast power switching.

In order to save DC power consumption and improve PAE each of the 6 gates can be individually driven at a different bias voltage. In this case, when using the targeted RF signal (modulated carrier), the distortion is monitored while adjusting VG1N,VG2N, VG3N, VG1S, VG2S and VG3S. The global strategy is to introduce all the distortion allowed by the targeted standard in the last stage of the amplifier by adjusting VG3N, VG3S while VG1N, VG1S, VG2N, VG2S are positioned in such a way that the 2 first stages of each line-up are kept at a neglectable contribution to the global distortion. An additional amount of DC power supply can be saved in fine tuning the drain voltages VD1N,VD2N, VD3N, VD1S, VD2S and VD3S while following the same procedure and the same strategy as described above. In order to validate each stage of the amplifier, with respect to the DC, it is recommended to set VGNS or VGNN (N =1,2,3) to -2.5V, then to set first the corresponding drain voltage VDNL or VDNH (N =1,2,3) to +1V and check that the corresponding IDNL or IDNH (N =1,2,3) drain current stay at a very low level, after that verification, VDNL or VDNH (N =1,2,3) can be set to 4.5V. When VGNL or VGNH (N =1,2,3) is changed from -2.5 to - 0.3V, the corresponding drain current IDNL or IDNH increases slowly in a controlled manner to reach the typical targeted value. Each gate can be randomely and independently positionned, no particular order is required.

9 Preliminary Datasheet 9 / 13 DIE LAYOUT AND PIN CONFIGURATION In order to enable to access voltage drain, an additionnal sense pad have been implemented on each drain voltage. The customer is free to use it or not. Due to design constraints, VG3N and VG3S signals have been implemented twice and named VG3N2 and VG3S2. During testings used only VG3N and VG3S, no guaranty is provided regarding the use of VG3N2 and VG3S2.
