HMC531LP5 / 531LP5E
MMIC VCO w/ HALF FREQUENCY OUTPUT
& DIVIDE-BY-4, 13.6 - 14.9 GHz
v04.0811
General Description
Features
Functional Diagram
The HMC531LP5 & HMC531LP5E are GaAs InGaP
Heterojunction Bipolar Transistor (HBT) MMIC VCOs.
The HMC531LP5 & HMC531LP5E integrate resona-
tors, negative resistance devices, varactor diodes
and feature half frequency and divide-by-4 outputs.
The VCO’s phase noise performance is excellent over
temperature, shock, and process due to the oscillator’s
monolithic structure. Power output is +7 dBm typical
from a +5V supply voltage. The prescaler function can
be disabled to conserve current if not required. The
voltage controlled oscillator is packaged in a leadless
QFN 5x5 mm surface mount package, and requires no
external matching components.
Dual Output: Fo = 13.6 - 14.9 GHz
Fo/2 = 6.8 - 7.45 GHz
Pout: +7 dBm
Phase Noise: -110 dBc/Hz @100 kHz Typ.
No External Resonator Needed
32 Lead 5x5mm SMT Package: 25mm²
Typical Applications
Low noise MMIC VCO w/Half Frequency, Divide-by-4
Outputs for:
• VSAT Radio
• Point to Point/Multipoint Radio
• Test Equipment & Industrial Controls
