Evaluation Board – artworks and NC drill output can be

provided if required).

Figures 1, 2 and 3 show the schem atic and copper

layout of a double-sided printed circuit board suitable

for evaluation of the device in the laboratory.

Pow er supply filtering

For the power supply filtering, low inductance surface

m ount capacitors are norm ally required. It has been

found that very good RF decoupling is provided on

each supply using a 1000pF NPO size 0805 or sm aller

ceram ic surface m ount capacitor, closest to the device

pin, with an adjacent 0.1µF X7R capacitor. Other

configurations are possible and it m ay be found that a

single 0.01uF X7R capacitor on each supply gives good

results. However this should be supported by larger

decoupling capacitors elsewhere on the printed circuit

board. Values of 1 to 10 µF are recom m ended,

particularly where the voltage regulators are located

m ore than a few inches from the device. These larger

capacitors are recom m ended to be solid tantalum

electrolytic or ceram ic types.

BNC connector sockets allow connection to test

instrum ents via 50⍀ cables. The output circuit includes

a resistor m atching circuit to present a load of 150⍀ to

the am plifier (equivalent to a 75⍀ back-term inated

video line) and sim ultaneously provide 50⍀ output

im pedance.

The attenuation of this m atching circuit is 15.45 dB. As

the am plifier is configured for a voltage gain of 2, the

overall gain is:

6 - 15.45 = -9.45dB.
