Local Oscillator for Wireless Transceiver
Variable frequency Large voltage swing to drive mixers Low power dissipation and low voltage operation (3.0 v) Precise quadrature outputs for single sideband applications Low phase noise

LO LO Phase noise produces adjacent Phase noise degrades receiver sensitivity due to reciprocal mixing channel interference in the transmitter
