HMC794LP3E v00.0709 Frequency Dividers & Detectors - SMT 4 2 GHz LOW NOISE PROGRAMMABLE DIVIDER (N = 1 to 4) Typical Applications Features The HMC794LP3E is ideal for: Low Noise Floor: -163 dBc/Hz at 10 MHz offset and -160 dBc/Hz at 100 kHz offset • LO Generation with Low Noise Floor Programmable Frequency Divider, N = 1, 2, 3 or 4 • Clock Generators 200 MHz to 2 GHz Input Frequency Range • Mixer LO Drive 50% Duty Cycle Outputs • Military Applications Up to +10 dBm Output Power • Test Equipment Sleep Mode: Consumes <1 µA • Sensors 16 Lead 3X3 mm SMT Package: 9mm2 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%. Electrical Specifications, TA = +25° C, Vcc = +5V, Zo = 50Ω, Bias1 = GND Parameter Conditions Min. Typ. Max.

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.
