The SKY65028-70LF achieves a high linearity and superior
Adjacent Channel Power Rejection/Adjacent Channel Leakage Ratio
(ACPR/ACLR) performance. This makes it ideal for use in the driver
stage of infrastructure transmit chains for Trans-European Trunked
Radio (TETRA) transceivers, multi-band (GSM, AMPS, PCS, DCS)
handsets, and many other wireless applications.
