Amplifier, Power, 13W 0.7-2.5 GHz MAAP-000077-PED000 Rev — Preliminary Datasheet Features ♦ 13 Watt Saturated Output Power Level ♦ Eutectically Mounted to Heat Spreader ♦ Next level integration is a Silver Epoxy-Based Process ♦ Variable Drain Voltage (6-10V) Operation ♦ MSAG™ Process Description The MAAPGM0077-PED000 is a 2-stage 13W power amplifier with on-chip bias networks eutectically mounted on a 10-mil thick Copper Molybdenum (CuMo) pedestal. This product is fully matched to 50 ohms on both the input and output. It can be used as a power amplifier stage or as a driver stage in high power applications. Fabricated using M/A-COM’s repeatable, high performance and highly reliable GaAs Multifunction Self-Aligned Gate (MSAG™)Process, each device is 100% RF tested at the die-on-pedestal assembly level to ensure performance compliance. M/A-COM’s MSAG™ process features robust silicon-like manufacturing processes, planar processing of ion implanted transistors, multiple implant capability enabling power, low-noise, switch and digital FETs on a single chip, and polyimide scratch protection for ease of use with automated manufacturing processes. The use of refractory metals and the absence of platinum in the gate metal formulation prevents hydrogen poisoning when employed in hermetic packaging.

Amplifier, Power, 13W 0.7-2.5 GHz MAAP-000077-PED000 Rev — Preliminary Datasheet Next Level Assembly Instructions: Pedestal Die Attach: The following paragraphs detail recommendations and instructions for the integration of the die on pedestal (IC assembly) and mating substrates to the next level assembly. These recommendations are summarized pictorially in Figure 19. To attach the die/pedestal assembly to the next level assembly, use a high thermal conductivity silver loaded epoxy. Two epoxies are recommended for this purpose, Diemat (www.diemat.com) PNs DM6030HK and DM4030LD with bulk thermal conductivities of 60 and 15 W/m-ºC, respectively. Silver-filled epoxies with conductivities < 10 W/m-ºC are not recommended for use in attaching these IC assemblies. DM6030HK is recommended for use when the coefficient of thermal expansion (CTE) of the material to which the IC assembly is to be attached is similar to that of CuMo (CTE ~ 7ppm). A next level assembly attach material with a CTE range of 4-10ppm would be acceptable. DM4030LD is recommended when the CTE of the next level assembly material is significantly greater than CuMo, e.g, Copper and Aluminum with CTEs of 14 and 23 ppm, respectively. Bondline thickness, the as-cured thickness of the silver epoxy layer between the IC assembly and next level assembly attach surface, is a critical parameter in terms of device performance and reliability. Bondline thickness should be maintained between 1 and 1.5 mils. A bondline thickness of < 1 mil reduces the sheer strength of the mechanical attach. Bondline thicknesses > 1.5 mils impacts in an incremental fashion the junction temperature of the IC and thereby the MTTF. The pedestal thickness used in the IC assembly is set at 10 mils such that the final IC assembly thickness is ~ 14 mils making it approximately planar with a mating substrate of 15 mil alumina, a thickness commonly used through X-band. This surface planarity was an objective because it results in shorter RF bond wire lengths between the IC assembly RF I/O and the mating substrate transmission line. Long bond wires can shift the load impedance required for ideal power transfer. Shorter RF bond wires result in improved RF performance. In any nominal microelectronic manufacturing environment, the process of silver epoxy attach of substrates and IC assemblies to the next level assembly can result in variable epoxy squeeze-out or run-out at the substrate or IC assembly peripheries. This variability, if not compensated for in the design of the overall assembly, can result in a high number of assembly failures due to epoxy wicking. This wicking process can occur when a mating substrate and IC assembly are placed too close to each other. To avoid this occurrence, a designed-in 5-10 mil spacing between the IC assembly and mating substrates is recommended. 8 Wirebonding: Bond @ 160°C using standard ball or thermal compression wedge bond techniques. For DC pad connections, use either ball or wedge bonds. For best RF performance, use wedge bonds of shortest length, although ball bonds are also acceptable.
