3 table 2: absolute mimimum and maximum ratings electrical characteristics stresses in excess of the absolute ratings may cause permanent damage. functional operation is not implied under these conditions. exposure to absolute ratings for extended periods of time may adversely affect reliability. table 3: operating ranges notes: 1. pins 2, 4, 5 and 7 should be ac-coupled. no external dc bias should be applied. 2. pin 6 should be ac-grounded and/or pulled to ground through a resistor for current control. 3. pins 11 and 14 are bias feeds for input amplifers 1a and 1b. no external dc bias should be applied. 4. pins 10 and 15 receive dc bias directly from pins 11 and 14. the device may be operated safely over these conditions; however, parametric performance is guaranteed only over the conditions defined in the electrical specifcations. parameter min max unit supply (pins 12, 13) rf power at inputs (pins 4, 5) dbmv storage temperature +150 soldering temperature soldering time sec parameter min typ max unit supply: v (pins 12, 13) voltage at i set (pin 6) +3 rf frequency case temperature +110 data sheet - rev 2.5 04/2012 aca2407e
