Functional Diagram General Description
the HMc794LP3e is a siGe BicMos low noise programmable frequency divider in a 3x3mm lead- less surface mount package. the circuit can be s & D programmed to divide from n = 1 to n = 4 in the r 200 MHz to 2 GHz input frequency range. the high e level output power (up to 10 dBm) with a very low iD ssB phase noise and 50% duty cycle makes this device ideal for low noise clock generation, Lo iv generation and Lo drive applications. configurable bias controls al ow power minimization of up to 20%. y D c n e u q e r
