Product Description
Sirenza Microdevices' SDM-09120 130W power module is a robust impedance matched, single-stage, push-pull Class AB amplifier module suitable for use as a power amplifier driver or output stage. The power transistors are fabricated using Sirenza's latest, high performance LDMOS process. It is a drop-in, no-tune solution for high power applications requiring high efficiency, excellent linearity, and unit-tounit repeatability. It is internally matched to 50 ohms.

Note 1: Internal RF decoupling is included on all bias leads. No additional bypass elements are required, however some applications may require energy storage on the VD leads to accommodate modulated signals. Note 2: Gate voltage must be applied to VGS leads simultaneously with or after application of drain voltage to prevent potentially destructive oscillations. Bias voltages should never be applied to a module unless it is properly terminated on both input and output. Note 3: The required VGS corresponding to a specific IDQ will vary from module to module and may differ between VGS1 and VGS2 on the same module by as much as 0.10 volts due to the normal die-to-die variation in threshold voltage for LDMOS transistors.

Note 4: 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. Note 5: This module was designed to have it's leads hand soldered to an adjacent PCB. The maximum soldering iron tip temperature should not exceed 700 C, and the soldering iron tip should not be in direct contact with the lead for longer than 10 seconds. Refer to app note AN054 (www.sirenza.com) for further installation instructions.
Operation of this device beyond any one of these limits may cause permanent damage. For reliable continuous operation see typical setup values specified in the table on page one.
Caution: ESD Sensitive
Appropriate precaution in handling, packaging and testing devices must be observed.
