The two stage MESFET design utilizes Motorola's planar refractory gate process to allow high performance GaAs to be applied to consumer applications. The proprietary PFP-16 package assures good grounding and low thermal resistance. As shown in Figure 1, the gate voltage pins can be ganged together and one voltage applied to both gates to set the quiescent operating current. Alternatively, VG1 and VG2 can be set separately. VD1 can be used as power control with a 45 dB per volt sensitivity. The placement of C3 in the VD1 supply line can be varied to optimize RF performance since T2 is part of a shunt L matching section. On the output, pins 11, 12 and 13, the placement of C11 is adjusted for best RF performance. Layout is important for amplifier stability and RF performance. Ground vias must be located as close to circuit ground connections as possible. Power supply bypassing C3, C6, C9, and C10 must be included to reduce out-of- band gain and prevent spurious output. Evaluation Boards Evaluation boards are available for RF Monolithic Integrated Circuits by adding a "TF" suffix to the device type.
