GENERAL DESCRIPTION

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

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 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

However, use dc blocking capacitors if the terminated system

The HMC911 is available in a RoHS-compliant, 24-terminal,

ceramic, leadless chip carrier.
