Overdrive and slew rate dispersion is typically 10 ps, making the HMC674LP3E ideal for a wide range of applications from ATE to broadband communications. The RSPECL output stages directly drive 400 mV into a 50 Ω resistor terminated to VTT= (VCCO− 2.0 V), where VTTis the PECL termination voltage (see Figure 16). The HMC674LP3E feature a high speed latch and programmable hysteresis.

HMC678SMT 13 Gbps, 2:1 Selector | RF Misc ICs and Modules | 4 | Active | The HMC678LC3C is a 2:1 Selector designed to support data transmission rates of up to 13 Gbps, and selector port operation of up to 13 GHz. The selector routes one of the two single-ended inputs to the differential output upon assertion of the proper select port. All single-ended input signals to the HMC678LC3C are terminated with 50 ohms to ground on-chip, and may be either AC or DC coupled.The outputs of the HMC678LC3C may be operated either differentially or single-ended. Outputs can be connected directly to a 50 ohm terminated system, while DC blocking capacitors may be used if the terminating system is 50 ohms to a non-ground DC voltage. The HMC678LC3C operates from a single -3.3V dc supply and is available in a ceramic RoHS compliant 3x3 mm SMT package.APPLICATIONS2:1 Multiplexer up to 13 GbpsRF ATE ApplicationsBroadband Test & MeasurementSerial Data Transmission up to 13 GbpsRedundant Path SwitchingBuilt-in Test |
HMC6787AGaAs MMIC I/Q Upconverter, 37 - 40 GHz | RF Misc ICs and Modules | 2 | Active | The HMC6787ALC5A is a compact GaAs MMIC I/Q variable gain upconverter in a leadless RoHS compliant SMT package. This device provides a small signal conversion gain of 11 dB with 17 dBc of sideband rejection, and 13 dB of gain control. The HMC6787ALC5A utilizes a RF variable gain amplifier preceded by an I/Q mixer where the LO is driven by a X2 multiplier. IF1 and IF2 mixer inputs are provided and an external 90° hybrid is needed to select the required sideband. The I/Q mixer topology reduces the need for filtering of the unwanted sideband. The HMC6787ALC5A is a much smaller alternative to hybrid style single sideband upconverter assemblies and it eliminates the need for wire bonding by allowing the use of surface mount manufacturing techniques.APPLICATIONSPoint-to-Point and Point-to-Multi-Point RadioMilitary Radar, EW & ELINTSatellite CommunicationsSensors |

HMC67926 GHz, T Flip-Flop with RESET & Programmable Output Voltage | RF Misc ICs and Modules | 1 | Obsolete | The HMC679LC3C is a T Flip-Flop w/Reset designed to support clock frequencies as high as 26 GHz. During normal operation, with the reset pin not asserted, the output toggles from its prior state on the positive edge of the clock. This results in a divide-by-two function of the clock input. Asserting the reset pin forces the Q output low regardless of the clock edge state (asynchronous reset assertion). Reversing the clock inputs allows for negative-edge triggered applications.The HMC679LC3C also features an output level control pin, VR, which allows for loss compensation or for signal level optimization. All input signals to the HMC679LC3C are terminated with 50Ω to ground on-chip, and may be either AC or DC coupled. Outputs can be connected directly to a 50Ω terminated system, while DC blocking capacitors may be used if the terminating system is 50Ω to a non-ground DC voltage. The HMC679LC3C operates from a single -3.3V dc supply and is available in a ceramic RoHS compliant 3x3 mm SMT package.APPLICATIONSSerial Data Transmission up to 26 GbpsHigh Speed Frequency Divider (up to 26 GHz)Broadband Test & MeasurementRF ATE Applications |
