Please confirm additional details regarding operation of these products from the formal specification sheet. For copies of the formal specification sheets, please contact one of our sales offices from the list of contact addresses listed on the last page for further information. 02.RA series products (RF power amplifier modules) and RD series products (RF power transistors) are designed for consumer mobile communication terminals and were not specifically designed for use in other applications. In particular, while these products are highly reliable for their designed purpose, they are not manufactured under a quality assurance testing protocol that is sufficient to guarantee the level of reliability typically deemed necessary for critical communications elements. Examples of critical communications elements would include transmitters for base station applications and fixed station applications that operate with long term continuous transmission and a higher on-off frequency during transmitting, especially for systems that may have a high impact to society. 0.RA series and RD series products use MOSFET semiconductor technology. They are sensitive to ESD voltage therefore appropriate ESD precautions are required. 04.In order to maximize reliability of the equipment, it is better to keep the devices temperature low. It is recommended to utilize a sufficient sized heat-sink in conjunction with other cooling methods as needed (fan, etc.) to keep the case temperature for RA series products lower than deg/c under standard conditions, and less than 90deg/C under extreme conditions. 05.RA series products are designed to operate into a nominal load impedance of ohms. Under the condition of operating into a severe high load VSWR approaching an open or short, an over load condition could occur. In the worst case there is risk for burn out of the transistors and smoking of other parts including the substrate in the module. 06.The formal specification includes a guarantee against parasitic oscillation under a specified maximum load mismatch condition. The inspection for parasitic oscillation is performed on a sample basis on our manufacturing line. It is recommended that verification of no parasitic oscillation be performed at the completed equipment level also. 0.For specific precautions regarding assembly of these products into the equipment, please refer to the supplementary items in the specification sheet. 08.Warranty for the product is void if the products protective cap (lid) is removed or if the product is modified in any way from it s original form. 09.For additional Safety first in your circuit design and notes regarding the materials, please refer the last page of this manual. 10.Please refer to the additional precautions in the formal specification sheet ± ± ± ±0.8.86±0.8 RF Input(Pin) Gate Voltage(VGG) R1.5±0.
