PA85

AN PA85 AN PA85 Power Amplifier Support Components EVALUATION KIT EK09 is an easy to use engineering platform for prototype evaluation. Provided items include: PC boards to make a five sided box, cage jacks and 200V ceramic bypass capacitors. The top board has pads for two TO-3 packages and one MO127 package. Two ends of the box are predrilled for banana jacks and BNC connectors (not supplied). Amplifiers and heatsinks are sold separately. HEATSINKS The following heatsinks are mechanically compatible with this amplifier. Thermal ratings are for optimum mounting in free air. HS03 1.7°C/W HS01 11.6°C/W HS04 0.95°C/W HS02 4.5°C/W HS05 0.85°C/W Copyright © Apex Microtechnology, Inc. 2012 www.apexanalog.com AN PA85U (All Rights Reserved) NOV 2012 AN PA85U REVB1 AN PA85 HS09 11.7°C/W HS14 2°C/W CAGE JACKS HS11 0.68°C/W With liquid cooling the HS11 thermal rating can be reduced to .1°C/W. MS02 Part number MS02 consists of a package of 8 cage jacks. These are mounted directly in a print circuit board. Use a spacer between the PCB and the heatsink to avoid short circuits. HS13 1.48°C/W 2 AN PA85U AN PA85 SOCKET MS03 NOTES: 1. Base material is aluminum, 0.002” thick. Do not allow the washer to touch pins of the amplifier. 2. For optimum thermal transfer, avoid abrasive handling of washers which can damage their 0.5mil thick layer of thermal compound with which each side is coated. 3. The dry thermal compound will flow filling header to heatsink voids as soon as the material reached 60°C. 4. Do not store unused thermal washers above 40°C. 5. A new washer must be used for each mounting. 6. Part number TW03 consists of a package of 10 washers. 7. Thermal resistance is 0.1°C/W. THERMAL WASHER TW03 NEED TECHNICAL HELP? CONTACT APEX SUPPORT!
