GaAs HBT PROGRAMMABLE 5-BIT COUNTER, DC - 2.2 GHz Evaluation PCB
4 4 t t M M s s s - s - r r o o t t c c e e t t e e s & D s & D r r e The circuit board used in the application should use RF circuit design techniques. Signal lines should have 50 e iD Ohm impedance while the package ground leads and backside ground slug should be connected directly to iD iv the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and iv bottom ground planes. The evaluation circuit board shown is available from Hittite upon request. y D y D c c n n e e u
