2400 MHz Application
This application was designed to provide NF =1.5 dB, S21 gain > 16 dB, OIP3 of 17.5 dBm with return
losses better than -9 dB at 2400 MHz. Typical performance that can be expected from this circuit at 2.7V
is listed in Table 9 . Two values of bias resistor R1 are shown to demonstrate performance for different IP3
and Icc requirements. 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.
Figure 9 is the 2400 MHz application schematic with package pinouts and the circuit component topology.
