Features and Benefits

  • Very wide bandwidth to 24 GHz
  • Time delay range: 70 ps typical
  • Single-ended or differential operation
  • Adjustable differential output amplitude with 780 mV p-p typical at 10 GHz
  • Delay control modulation bandwidth: 1.6 GHz typical
  • Single supply: 3.3 V
  • 24-terminal ceramic, leadless chip carrier (LCC)

Product Details

The HMC911 is a broadband time delay with 62 ps to 75 ps continuously adjustable delay range to 24 GHz. The delay control is linearly monotonic with respect to the differential delay control voltage (VDCP and VDCN), and the control input has a modulation bandwidth of 1.6 Hz. The HMC911 provides a differential output voltage with constant amplitude for single-ended or differential input voltages above the input sensitivity level, and the output voltage swing can be adjusted using the VAC control pin.

The HMC911 features internal temperature compensation and bias circuitry to minimize delay variations with temperature. All RF inputs and outputs of the HMC911 are internally terminated with 50 Ω to VCC and can be ac-coupled or dc-coupled. Output pins connect directly to a 50 Ω to VCC terminated system. However, use dc blocking capacitors if the terminated system input is 50 Ω to a dc voltage other than VCC.

The HMC911 is available in a RoHS-compliant, 24-terminal, ceramic, leadless chip carrier.
