AMIS-53050
Frequency Agile Transceiver
Data Sheet
traces connecting other components away from the inductor and capacitor pads. Furthermore, the values of the inductor and/or the
capacitor are to be optimized in order to properly calibrate the PLL for a given frequency of operation.
The AMIS-53050 has an internal loop filter which is linked to the PLL circuit to generate the transceiver’s output frequency. There is an
option to use an external loop filter.
Note:
Using a capacitor in parallel with an inductor for the external VCO LC circuit will lower the VCO gain, reducing the frequency
overlap between the transmit frequency and the receive frequency. It is suggested that only a coil be used in the LC circuit, if possible.
Note:
The PCB traces to the external LC components need to be as symmetrical as possible.
Note:
The external L and C used to set the VCO frequency should be physically located as close to the AMIS-53050 Pins LOp, LOn as
possible.
