Functional Diagram
General Description
The HMC794LP3E is a SiGe BiCMOS low noise
programmable frequency divider in a 3x3mm leadless surface mount package. The circuit can be
programmed to divide from N = 1 to N = 4 in the
200 MHz to 2 GHz input frequency range. The high
level output power (up to 10 dBm) with a very low
SSB phase noise and 50% duty cycle makes this
device ideal for low noise clock generation, LO
generation and LO drive applications. Configurable
bias controls allow power minimization of up to 20%.

Pin Description (Continued)
Application Note:
The HMC794LP3E is a high performance RF divider. Such dividers are high gain devices with internal feedback.
The device will oscillate if used with AC coupled RF inputs and if no RF input is applied. Normally, 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 oscillate in divide 2, 3, or 4 modes with no RF input. In
general very small RF input levels will stop all oscillations. At the minimum rated RF input sensitivity level or higher,
no oscillations or spurious signals exist and excellent 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.

should have 50 ohm impedance while the package
ground leads and backside ground paddle should be
connected directly to the ground plane similar to that

used to connect the top and bottom ground planes.
