General Description
Features
Functional Diagram
The HMC505LP4 & HMC505LP4E are GaAs InGaP
Heterojunction Bipolar Transistor (HBT) MMIC VCOs
with integrated resonators, negative resistance
devices, varactor diodes, and buffer ampli ers.
Covering 6.8 to 7.4 GHz, the VCO’s phase noise
performance is excellent over temperature, shock and
vibration due to the oscillator’s monolithic structure.
Power output is +11 dBm typical from a single supply
of +3V @ 80 mA. The voltage controlled oscillator is
packaged in a leadless QFN 4x4 mm surface mount
package.
Pout: +11dBm
Phase Noise: -106 dBc/Hz @100 kHz
No External Resonator Needed
Single Supply: +3V @ 80 mA
