HMC515LP5

515LP5E
MMIC VCO w/ HALF FREQUENCY OUTPUT
& DIVIDE-BY-4, 11.5 - 12.5 GHz
v00.1005
General Description
Features
Functional Diagram
The HMC515LP5 & HMC515LP5E are GaAs InGaP
Heterojunction Bipolar Transistor (HBT) MMIC VCOs.
The HMC515LP5 & HMC515LP5E 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 +10 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 = 11.5 - 12.5 GHz
Fo/2 = 5.75 - 6.25 GHz
Pout: +10 dBm
Phase Noise: -110 dBc/Hz @100 kHz Typ.
No External Resonator Needed
