HMC905LP3E v00.0310 Frequency Dividers & Detectors - SMT 4 6 GHz LOW NOISE PROGRAMMABLE DIVIDER (N = 1 to 4) Typical Applications Features The HMC905LP3E is ideal for: Low Noise Floor: -164 dBc/Hz at 10 MHz Offset for N = 4 • LO Generation with Low Noise Floor Programmable Frequency Divider, N = 1, 2, 3 or 4 • Software Defined Radios 400 MHz to 6 GHz Input Frequency Range • Clock Generators Up to +6 dBm Output Power • Fast Switching Synthesizers Sleep Mode: Consumes <1 µA • Military Applications 16 Lead 3X3 mm SMT Package: 9mm2 • Test Equipment • Sensors Functional Diagram General Description The HMC905LP3E is a SiGe BiCMOS low noise programmable frequency divider in a 3x3 mm leadless surface mount package. The circuit can be programmed to divide from N = 1 to N = 4 in the 400 MHz to 6 GHz input frequency range. The high level output power (up to 6 dBm single ended) 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 and output power controls allow current consumption and output power control. The device incorporates a power down feature, good input to output isolation and fast start up time. The HMC905LP3E can be included into fast switching “ping-pong” applications. Electrical Specifications, TA = +25° C, Vcc = +3.3V, Zo = 50Ω Parameter Conditions Min. Typ. Max.

Interface Schematic Application Note: The HMC905LP3E 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 400 MHz, square wave input signal is recommended. For applications where the input frequency is bigger than ~5.5 GHz, it is recommended either to use differential drive, or to increase the divider core current (bias settings BIAS1BIAS0=01 or 10). For single ended applications, apply the signal on the positive input RFinp and terminate the unused output with 50 ohms.
