Figure 6. Block diagram of the 2 GHz production test board used for NF, Gain, OIP3 , P1dB and PAE and ACLR measurements. This cir-
cuit achieves a trade-off between optimal OIP3, P1dB and VSWR. Circuit losses have been de-embedded from actual measurements.
A
= 25°C, DC bias for RF parameters is Vds = 4.5V and Ids = 200 mA unless otherwise specified.
