Assembly Notes
Independent of the bias applied to the package, the
backside of the package should always be connected
to both a good RF ground plane and a good thermal
heat sinking region on the PC–board to optimize
performance. For single–ended output operation the
unused RF output lead should be terminated into 50Ω
to a contact point at the V
through a dc blocking capacitor.
A minimum RF and thermal PC board contact area
equal to or greater than 2.67 x 1.65 mm (0.105" x
0.065") with eight 0.020" diameter plated–wall thermal
vias is recommended.
MMIC ESD precautions, handling considerations, die
attach and bonding methods are critical factors in
successful GaAs MMIC performance and reliability.

#18,
To operate component from a negative supply, ground each
V CC connection and supply V EE with a negative voltage (-4.5
to -6.5v) bypassed to ground with ~ 1 m f capacitor.
RF out should be terminated in 50Ω to ground. (dc blocking
capacitor required for positive bias configuration.)
