As a direct result of their circuit topology, the performance of INA MMICs is extremely sensitive to groundpath ("emitter") inductance. The two stage design creates the possibility of a feedback loop being formed through the ground returns of the stages. If the path to ground provided by the external circuit is "long" (high in impedance) compared to the path back through the ground return of the other stage, then instability can occur (see Fig. 1). This phenomena can show up as a "peaking" in the gain versus frequency response (perhaps creating a negative gain slope amplifier), an increase in input VSWR, or even as return gain (a The "bottomline" is that excellent grounding is critical when using INA MMICs. The use of plated through holes or equivalent minimal path ground returns at the device is essential. An appropriate layout is shown in Figure 2. A corollary is that designs should be done on the thinnest practical substrate. The parasitic inductance of a pair of via holes passing through 0.032" thick P.C. board is approximately 0.1 nH, while that of a pair of via holes passing through 0.062" thick board is close to 0.5 nH. HP does not recommend using INA family MMICs on boards thicker than 32 mils. Figure 1. INA Potential Ground Loop. These stability effects are entirely predictable. A circuit simulation using the data sheet S-parameters and including a description of the ground return path (via model or equivalent "emitter" inductance) will give an accurate picture of the performance that can be expected. Device characterizations are made with the ground leads of the MMIC directly contacting a solid copper block (system ground) at a distance of 2 to 4 mils from the body of the package. Thus the information in the data sheet is a true description of the performance capability of the MMIC, and contains minimal contributions from fixturing. Figure 2.
