730 MHz Closed Loop Buffer

Printed Circuit Layout

As with any high-frequency device good PCB

layout is necessary for optimum performance

This is especially important for the EL2072

which has a typical bandwidth of 730 MHz

Ground plane construction is a requirement as is

good power-supply bypassing close to the pack-

age A closely-placed 0 01 mF ceramic capacitor

between each supply pin and the ground plane is

usually sufficient decoupling

Pins 2 3 6 and 7 should be connected to the

ground-plane to minimize capacitive feed-

through and all input and output traces should

be laid out as transmission lines and terminated

as close to the EL2072 package as possible

2072 – 4

Increasing capacitance on the output of the

EL2072 will add phase shift decreasing phase

margin and increasing frequency-response peak-

ing A small series resistor before the capacitance

decouples this effect and should be used for large

capacitance values Please refer to the graphs for

the appropriate resistor value to be used
