Functional Diagram
General Description
The HMC877LC3 is a phase shifter/time delay with
0 to 500°(1.4 UI) continuously adjustable shift/delay
range. The delay control is linearly monotonic with
respect to the differential control voltage (VDCP,
VDCN) and the control input has a modulation band-
width of 2.5 GHz. 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 HMC877LC3
features internal temperature compensation and bias
circuitry to minimize delay variations with temperature.
The device also features a delay control voltage range
adjustment pin, LC. All RF input and outputs of the
HMC877LC3 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. The HMC877LC3 is avail-
able in ROHS-compliant 3x3 mm SMT package.
