By eliminating the complex tuning and assembly processes typically required by hybrid (discrete-FET) amplifiers, the AMMC-5023 is a cost-effective alternative in both 21.2–23.6 GHz and 24.5–26.5 GHz communications receivers. The device has good input and output match to 50 Ohm and is unconditionally stable to more than 40 GHz. The backside of the chip is both RF and DC ground. This helps simplify the assembly process and reduces assembly related performance variations and costs. It is fabricated in a PHEMT process to provide exceptional noise and gain performance.

Data obtained from on-wafer measurements. 6 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 VD1 drain supply. Similarly, the two output stages are biased with the VD2 supply. Standard LNA operation is with a single positive DC drain supply voltage (VD1 =VD2 = 5 V) as shown in the assembly diagram, Figure 2(a). If desired, the output stage DC supply voltage (VD2) can be increased to improve output power capability while maintaining optimum low noise bias conditions for the input section. The output power may also be adjusted by applying a positive voltage at VG2 to alter the operating bias point for both the output FETs. Increasing the voltage applied to VG2 (more positively) results in a more negative gateto-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 conductive epoxy, the amount should be just enough to provide a thin fillet around the bottom perimeter 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 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 VG1 VD1 VG2 VD2 Figure 19.
