ONSIDERATIONS
The gain block is self-biased by the voltage that is present
on pin 5 (V
BIAS
). Chart 1 shows the quiescent current vs. bias
voltage characteristic. Chart 2 shows device characteristics
when operated with a 5v supply and with different values of
external resistor. Using Chart 2 it is possible to trade-off Gain
and P1dB compression point for supply current.
Supply voltages other than 5v may be accommodated by
adjusting the value of the external resistor to produce the
same quiescent current as the 5v case. To calculate the
resistor required for a different supply voltage use the
following formula:
EXT
EXT
BIAS
BIAS
R
(V1)=R
(5V)(V1-V
) (5-V
)
Where V
BIAS
is the Pin 5 bias voltage obtained from
Chart 1and V1 is the desired supply voltage.
