2140 MHz Application
These application circuits demonstrate performance at 2140 MHz. Matching component values can be
changed to enhance a particular parameter. Typical performance expected from this circuit at 2.75V Vcc
is listed in Table 8 . Two values of bias resistor R1 are shown to demonstrate performance for different IP3
and Icc requirements. The same matching topology is used on each of the application circuits, with a
highpass match on the output and a simple inductor-capacitor network on the LNA input. Resistor R3 is
used to de-Q output inductor L2 and adjust gain and return losses. Lowering the value of R3 lowers gain
and improves return losses.
