10 GHz LATCHED COMPARATOR

WITH RSPECL OUTPUT STAGE

the circuit board used in the application should

use rF circuit design techniques. signal lines

should have 50 ohm impedance while the pack-

age ground leads should be connected directly to

the ground plane similar to that shown. a sufficient

number of via holes should be used to connect the

top and bottom ground planes in order to provide

good rF grounding to 10 GHz. the evaluation

circuit board shown is available from Hittite upon

request.
