| Summary: | The consumer demands on having multifunctional
wireless communication devices have driven
current mobile handset to be more complex than it has
ever been before. In particular, radio frequency (RF)
front-end has evolved to adapt with multi-standards
terminals. Thus, by having integrated switches and
resonators on the same chip may be considered as a
compact solution. In this paper, the design and simulation
of RF-CMOS SPST switch is presented. The switch
exhibits insertion loss of 1.15-dB and 1.155-dB at 850MHz
and 1.125GHz respectively. On the other hand, the
isolation is > 22dB in this frequency range while its P1dB
is > 20dBm. Pre and post layout of the switch is included in
this paper to observe the effect of parasitic capacitance in
the layout design. |
