EL2072
Burn-In Circuit
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
730MHz. Ground plane construction is a requirement, as is
good power-supply bypassing close to the package. A
closely-placed 0.01µF 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 feedthrough, and all input and output
traces should be laid out as transmission lines and
terminated as close to the EL2072 package as possible.
Increasing capacitance on the output of the EL2072 will add
phase shift, decreasing phase margin and increasing
frequency-response peaking. 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.
