Exceeding any one or combination of these limits may cause permanent damage to this device. 2. M/A-COM does not recommend sustained operation near these survivability limits. 3. Case Temperature (TC) = +85°C 4. Nominal bias is obtained by first connecting -2.4 volts to pin 5 or pin 6 (VGG), followed by connecting +8 volts to pin 1 or pin 10 (VDD). Note sequence. Adjust VGG for a drain current of 500 mA typical. 5. RF ground and thermal interface is the flange (case bottom). Adequate heat sinking is required. 6. No DC bias voltage appears at the RF ports. 7. No DC resistance at the input and output ports is a short circuit. No voltage is allowed on these ports. 8. For optimum IP3 performance, the VDD bypass capacitors should be placed within 0.5 inches of the VDD leads. 2 ADVANCED: Data Sheets contain information regarding a product M/A-COM Technology Solutions • North America Tel: 800.366.2266 / Fax: 978.366.2266 is considering for development.
