7 biasing and operation the AMMC-5023 has four cascaded gain stages as shown in figure 19. the first two gain stages at the input are biased with the v d1 drain supply. similarly, the two output stages are biased with the v d2 supply. standard lna operation is with a single positive dc drain supply voltage (v d1 =v d2 = 5 v) as shown in the assembly diagram, figure 2(a). if desired, the output stage dc supply voltage (v d2 ) can be increased to improve output power capability while maintain- ing optimum low noise bias conditions for the input section. the output power may also be adjusted by applying a positive voltage at v g2 to alter the operat- ing bias point for both the output fets. increasing the voltage applied to v g2 (more positively) results in a more negative gate- to-source voltage and, therefore, lower drain current. figures 20(b) and 20(c) illustrate how the device can be assembled for independent drain supply operation and for output stage gate bias control. assembly techniques the chip should be attached directly to the ground plane using either a fluxless ausn solder preform or electrically conductive epoxy [1] . for conduc- tive epoxy, the amount should be just enough to provide a thin fillet around the bottom perim- eter of the die. the ground plane should be free of any residue that may jeopardize electrical or mechanical attachment. caution should be taken to not exceed the absolute maximum rating for assembly temperature and time. thermosonic wedge bonding is the preferred method for wire attachment to the bond pads. the rf connections should be kept as short as possible to minimize inductance. gold mesh [2] or double-bonding with 0.7 mil gold wire is recommended. mesh can be attached using a 2 mil round tracking tool and a tool force of approximately 22 grams with an ultrasonic figure 19. AMMC-5023 schematic. power of roughly 55 db for a duration of 76 8 ms. a guided wedge at an ultrasonic power level of 64 db can be used for the 0.7 mil wire. the recommended wire bond stage temperature is 150 2 c. the chip is 100 mm thick and should be handled with care. this mmic has exposed air bridges on the top surface. handle at edges or with a custom collet (do not pick up die with vacuum on die center.) this mmic is also static sensitive and esd handling precautions should be taken. for more information, see agilent application note 54 gaas mmic esd, die attach and bonding guidelines. notes: 1. ablebond 84-1 lm1 silver epoxy is recommended. 2. buckbee-mears corporation, st. paul, mn, 800-262-3824. rf input rf output v g1 v d1 v g2 v d2
