BROADBAND TIME DELAY - ANALOG - SMT

HMC910LC4B
v0 3.1211
BROADBAND ANALOG
TIME DELAY, DC - 24 GHz
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.

Evaluation PCB
The circuit board used in the application should
use RF circuit design techniques. Signal lines
should have 50 Ohm impedance while the package
ground leads and exposed paddle should be con-
nected directly to the ground plane similar to that
shown. A sufficient number of via holes should be
used to connect the top and bottom ground planes.
The evaluation board should be mounted to an
appropriate heat sink. The evaluation circuit board
shown is available from Hittite upon request.
