Functional Diagram
General Description
The HMC505LP4 & HMC505LP4E are GaAs InGaP
Heterojunction Bipolar Transistor (HBT) MMIC VCOs
with integrated resonators, negative resistance devices,
varactor diodes, and buffer amplifiers. Covering 6.8
to 7.4 GHz, the VCO鈥檚 phase noise performance is
excellent over temperature, shock and vibration due
to the oscillator鈥檚 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.
