cations in the complex wave propagation environment. Similar radiation patterns for other frequencies over the operating band were also seen, and the results are not shown for brevity. Measured peak antenna gain and simulated (Ansoft HFSS) radiation efficiency versus frequency is shown in Figure 4.
## Abstract A 1.9โGHz CMOS differential power amplifier for polar transmitter applications is designed using a 0.25โฮผm RF CMOS process. The input transformer and output transformer are fully integrated on the chip. The transmission line transformer is used as an output power combiner and an output
