See Figure 5, Input Power versus Case Temperature REV 7 (c)MOTOROLA RF DEVICE DATA Motorola, Inc. 1995 MHW720A1 MHW720A2 1 APPLICATIONS INFORMATION Nominal Operation All electrical specifications are based on the nominal conditions of Vs1 (Pin 5) and Vs2 (Pin 3) equal to 12.5 Vdc and with output power equaling 20 watts. With these conditions, maximum current density on any device is 1.5 x 105 A/cm2 and maximum die temperature with 100 base plate temperature is 165. While the modules are designed to have excess gain margin with ruggedness, operation of these units outside the limits of published specifications is not recommended unless prior communications regarding intended use has been made with the factory representative. Gain Control This module is designed for wide range Pout level control. The recommended method of power output control, as shown in Figure 3, is to fix Vs1 and Vs2 at 12.5 Vdc and vary the input RF drive level at Pin 7. In all applications, the module output power should be limited to 20 watts. passed with a 0.018 F chip capacitor effective for frequencies from 5 through 470 MHz. For bypassing frequencies below 5 MHz, networks equivalent to that shown in the test fixture schematic are recommended. Inadequate decoupling will result in spurious outputs at certain operating frequencies and certain phase angles of input and output VSWR less than 4:1. Load Mismatch During final test, each module is load mismatch tested in a fixture having the identical decoupling network described in Figure 1. Electrical conditions are Vs1 and Vs2 equal 15.5 V, load VSWR infinite, and output power equal to 30 watts. Mounting Considerations To insure optimum heat transfer from the flange to heatsink, use standard 6-32 mounting screws and an adequate quantity of silicon thermal compound (e.g., Dow Corning 340). With both mounting screws finger tight, alternately torque down the screws to 4-6 inch pounds. The heatsink mounting surface directly beneath the module flange should be flat to within 0.005 inch to prevent fracturing of ceramic substrate material. For more information on module mounting, see EB-107. Decoupling Due to the high gain of the three stages and the module size limitation, the external decoupling network requires careful consideration.
