MAAP-015024

Note 1 - Biasing

The MAAP-015024 is biased directly through the

one side of the PA. The PA is biased typically with

and when switching off the PA the drain voltage

must be switched off first before the gate voltage.

It is strongly recommended to pulse the drain

voltage of the PA so the heat can be dissipated

from the device.

Note 2 - Bias Arrangement

capacitance of 100 pF as close to the device as

the side the gate voltage is applied. It is

recommended to also use a further capacitance of

0.01 µF on the DC pins.

Application Notes

Applications Section

Note 3 - Pulse Operation

The

performance

of

the

MAAP-015024

is

characterized under pulsed conditions with a pulse

width of 5 µS and a duty cycle of 5%.

The

measurements were taken while the drain voltage

was pulsed. It is strongly recommended to ensure

the heat generated is dissipated from the die with

an adequate thermal solution. If this thermal path

is not provided this will result in reduced

performance/lifetime and possible thermal runaway

that will permanently damage the PA. It is not

recommended to operate this PA in CW operation

unless the bias is reduced.
