SLD-2083CZ
Product Description
Sirenza Microdevices’ SLD-2083CZ is a robust 12 Watt high performance LDMOS transistor designed for operation to 2700MHz. It is an excellent solution for applications requiring high linearity and efficiency at a low cost. The SLD-2083CZ is typically used in the design of driver stages for power amplifiers, repeaters, and RFID applications. The power transistor is fabricated using Sirenza’s high performance XeMOS IITM process.

Pin Description
Pin # 1 2 Flange Function Gate Drain Source, Gnd Description Transistor RF input and gate bias voltage. 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 recommended maximum input power or voltage. . Transistor RF output and drain bias voltage. Typical voltage is 28V. 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.

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. 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.
