HMC910LC4B

BROADBAND ANALOG

TIME DELAY, DC - 24 GHz

v02.0910

General Description

Features

Functional Diagram

the 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, VdC and the control input has a

modulation bandwidth of 10 mHz. 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 minimize delay

variations with temperature. the device also features

an enable pin, enB. all rF input and outputs of the

HmC910lC4B are internally terminated with 50 ohms

to Vcc, and may either be aC or dC coupled. output

pins can be connected directly to a 50 ohm to Vcc

terminated system, while dC blocking capacitors must

be used if the terminated system input is 50 ohms to a

dC voltage other than Vcc.

Very Wide Bandwidth: dC - 24 gHz

Continuous adjustable delay range: 70 ps

Single-ended or differential operation

adjustable differential output Voltage

Swing: 170 - 760 mVp-p @ 24 gHz
