Application Note:
the HMc794LP3e is a high performance rF divider. such dividers are high gain devices with internal feedback. the device will oscil ate if used with Ac coupled rF inputs and if no rF input is applied. normal y, if the rF input signal is removed the device should be disabled, or it should be placed in divide by 1 mode. the device is stable in divide by one mode with no rF input. the device will oscil ate in divide 2, 3, or 4 modes with no rF input. in general very small rF input levels will stop all oscil ations. At the minimum rated rF input sensitivity level or higher, no oscil ations or spurious signals exist and excel ent low noise performance is achieved. For input frequency lower than 200 MHz, square wave input signal is recommended. the divider output power for the differential mode, shows a roll off at lower frequencies due to the limited frequency range of the t6 & t7 (4:1) rF transformers, 500 MHz to 3000 MHz.
