Circuit Layout. Co-Planar Waveguide Shunt Connection for HSMP-489x Series Co-Planar waveguide, with ground on the top side of the printed circuit board, is shown in Figure 20. Since it eliminates the need for via holes to ground, it offers lower shunt parasitic inductance and higher maximum attenuation when compared to a microstrip circuit.

Equivalent Circuit. Figure 17. Circuit Layout. Microstrip Shunt Connections for HSMP-489x Series In Figure 18, the center conductor of the microstrip line is interrupted and leads 1 and 2 of the HSMP-489x diode are placed across the resulting gap. This forces the 1.5 nH lead inductance of leads 1 and 2 to appear as part of a low pass filter, reducing the shunt parasitic inductance and increasing the maximum available attenuation. The 0.3 nH of shunt inductance external to the diode is created by the via holes, and is a good estimate for 0.032" thick material. 0.3 pF 0.75 nH Equivalent Circuit Model HSMP-389x Chip* Rs Figure 21.

(dimensions in inches). 0.037 0.95 0.037 0.95 SMT Assembly Reliable assembly of surface mount components is a complex process that involves many material, process, and equipment factors, including: method of heating (e.g., IR or vapor phase reflow, wave soldering, etc.) circuit board material, conductor thickness and pattern, type of solder alloy, and the thermal conductivity and thermal mass of components. Components with a low mass, such as the SOT package, will reach solder reflow temperatures faster than those with a greater mass. Agilent’s diodes have been qualified to the time-temperature profile shown in Figure 26. This profile is representative of an IR reflow type of surface mount assembly process. After ramping up from room temperature, the circuit board with components attached to it (held in place with solder paste) 0.079 2.0 passes through one or more preheat zones. The preheat zones increase the temperature of the board and components to prevent thermal shock and begin evaporating solvents from the solder paste. The reflow zone briefly elevates the temperature sufficiently to produce a reflow of the solder. The rates of change of temperature for the ramp-up and cooldown zones are chosen to be low enough to not cause deformation of the board or damage to components due to thermal shock. The maximum temperature in the reflow zone (TMAX) should not exceed 235°C. These parameters are typical for a surface mount assembly process for Agilent diodes. As a general guideline, the circuit board and components should be exposed only to the minimum temperatures and times necessary to achieve a uniform reflow of solder. 250 TMAX 0.035 0.9 DIMENSIONS IN inches mm Figure 24.
