The gate bias voltage must be temperature compensated to maintain constant bias current over the operating temperature range. Care must be taken to protect against video transients that exceed the maximum input power or voltage. 2 Drain Transistor RF output and drain bias voltage. Typical voltage 28V. Flange Source, Gnd Exposed area on the bottom side of the package needs to be mechanically attached to the ground plane of the board for optimum thermal and RF performance. See mounting instructions for recommendation. Pin Diagram Note 1: Gate voltage must be applied to VGS lead concurrently or after application of drain voltage to prevent potentially destructive oscillations. Bias voltages should never be applied to the transistor unless it is properly terminated on both input and output. ESD Protection Pin 1 Pin 2 Note 2: The required VGS corresponding to a specific IDQ will vary from device to device due to the normal die-to-die variation in threshold voltage withLDMOS transistors. Note 3: The threshold voltage (VGSTH) of LDMOS transistors varies with device temperature. External temperature compensation may be required. See Sirenza application notes AN-067 LDMOS Bias Temperature Compensation.
