MMIC DIVISION
General Description
Features
The MMVC92 MMIC VCO is designed in a
highly reliable InGaP-GaAs Hetero-Junction
Bipolar Transistor (HBT) process with active
device, integrated resonator, tuning diode and
isolating output amplifier on chip. The VCO’s
phase noise performance is good, according
to the oscillator’s monolithic structure.
• Low Phase Noise
• No External Resonator Needed
• Low Supply Voltage: 3.0 - 3.6 V
• Low Cost QFN24 Plastic Package
• Buffer Amplifier
• High Power Output
Packages
Functional Diagram
The MMIC is available in a QFN24 4x4mm²
package as well as pure die.

Applications
Low Noise MMIC for C-Band
Applications such as:
• IEEE 802.11 WLAN + HIPERLAN
• Satellite Communications
• Microwave Point-to-Point Radios
• Microwave Sensors
• other ISM Applications

For the final application proper RF circuit design techniques should be applied. All RF signal
traces should have 50 ohms. Provide (filled) vias under the package for both, sufficient RF
ground and heat dissipation. The evaluation board shown is available from Work Microwave
upon request. Also available a boxed version for phase noise measurements.
