Hittite’s HMC910LC4B is a broadband time delay with 0 to 70 ps continuously adjustable delay range.
The delay control is linearly monotonic with respect to the control voltage and the control input has a modulation bandwidth of 600 MHz. It operates from 3,3 V over the bandwidth from DC to 24 GHz and is housed in a 24-lead, 4 x 4 mm SMT package.
The device provides a differential output voltage with constant amplitude for single-ended or differential input voltages above the input sensitivity level, while the output voltage swing may be adjusted using the VAC control pin. The HMC910LC4B features internal temperature compensation and bias circuitry to minimise delay variations with temperature. It also features an enable pin. All RF input and outputs of the device are internally terminated with 50 Ω to VCC, and may either be AC or DC coupled.
