HMC401QS16G / 401QS16GE
v03.0810
KU-BAND MMIC VCO WITH DIVIDE-BY-8
13.2 - 13.5 GHz
General Description
Features
Functional Diagram
The HMC401QS16G & HMC401QS16GE are GaAs
InGaP Heterojunction Bipolar Transistor (HBT) MMIC
VCOs. The HMC401QS16G & HMC401QS16GE
integrate resonators, negative resistance devices,
varactor diodes and divide-by-8 prescalers. 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 voltage controlled
oscillator is packaged in a low cost, surface mount
16 leaded QSOP package with an exposed base for
improved RF and thermal performance.
Pout: -7 dBm
Phase Noise: -105 dBc/Hz @100 KHz Typ.
No External Resonator Needed
Single Supply: 5V @ 290 mA
QSOP16G SMT Package
Typical Applications
