HMC733LC4B
v04.0514
WIDEBAND MMIC VCO w/ BUFFER
AMPLIFIER, 10 - 20 GHz
General Description
Features
Functional Diagram
The HMC733LC4B is a wideband MMIC Voltage
Controlled Oscillator which incorporates the reson-
ator, negative resistance device, and varactor diode.
Output power and phase noise performance are
excellent over temperature due to the oscillator’s
monolithic construction. The Vtune port accepts
an analog tuning voltage from 0 to +22V. The
HMC733LC4B VCO operates from a single +5V supply,
consumes only 70 mA of current, and is housed in a
RoHS compliant SMT package. This wideband VCO
uniquely combines the attributes of ultra small size,
low phase noise, low power consumption, and wide
tuning range.
Wide Tuning Bandwidth
Pout: +3 dBm
Low SSB Phase Noise: -90 dBc/Hz @100 kHz
No External Resonator Needed
Single Positive Supply: +5V @ 70 mA
RoHS Compliant 4 x 4 mm SMT Package
Typical Applications
Low Noise wideband MMIC VCO is ideal for:
• Industrial/Medical Equipment
• Test & Measurement Equipment
• Military Radar, EW & ECM
