HMC508LP5
/
508LP5E
MMIC VCO w/ HALF FREQUENCY
OUTPUT 7.3 - 8.2 GHz
v00.0506
General Description
Features
Functional Diagram
The HMC508LP5 & HMC508LP5E are GaAs InGaP
Heterojunction Bipolar Transistor (HBT) MMIC
VCOs. The HMC508LP5 & HMC508LP5E integrate
resonators, negative resistance devices, varactor
diodes and feature a half frequency output. The VCO's
phase noise performance is excellent over temper-
ature, shock, and process due to the oscillator's
monolithic structure. Power output is +15.0 dBm typical
from a +5V supply. The voltage controlled oscillator
is packaged in a leadless QFN 5x5 mm surface
mount package, and requires no external matching
components.
Dual Output: Fo = 7.3 - 8.2 GHz
Fo/2 = 3.65 - 4.1 GHz
Pout: +15.0 dBm
Phase Noise: -116 dBc/Hz @100 kHz Typ.
No External Resonator Needed
QFN Leadless SMT Package, 25 mm
