WIDEBAND VCOS - SMT

HM C732LC4B
v02.0514
WIDEBAND MMIC VCO WITH BUFFER AMPLIFIER
6 - 12 GHz
General Description
Features
Functional Diagram
The HMC732LC4B is a wideband MMIC Voltage
Controlled Oscillator which incorporates the resonator,
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 +23V. The HMC732LC4B VCO
operates from a single +5V supply, consumes only
57 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: +1 dBm
Low SSB Phase Noise: -95 dBc/Hz @100 kHz
No External Resonator Needed
Single Positive Supply: +5V @ 57 mA
24 Lead Ceramic 4x4 mm SMT Package: 16 mm²
Typical Applications
