Functional Block Description
The PMB 2100 contains all circuits including resonators required for a LO1 VCO for a
dualband transceiver.
2.4.1
Seperate VCO cores are used for the two frequency bands. The band required can be
selected with the OSW pin. Both VCOs have a common frequency control input VTUNE
and a common voltage supply pin VCC.
VCO core
2.4.2
Seperate buffers are used for both cores to amplify the VCO signals. The Outputs are
combined into one output of the IC. A balanced Configuration is used for excellent even
harmonic suppression. The VCO can be connected to a chip out of the Infineon SMARTi
family with a minimum number of components.
